Abstract | A comparative analysis of the mud-pulse destruction efficiency of tough and sharp rocks in the ore industry relatively to the existing drilling and blasting technology, as well as the testing destruction processes by hypersonic steel and hollow charge projectiles is provided in the article. The reasoned explanations of the compared processes of the hypersonic projectiles introduction into the solid and the character of the volumetric breaking are given. The features of technical, social and economic efficiency of mud-pulse technology are listed in the mode of hypersonic interaction with the destroyed solid. The method and design of environmentally sound electric-discharge drive for mud-pulse devices primarily constructed for the strong rocks destruction is described. This method is demonstrated to involve rapid overheating of a part of weak electrolyte (for example, salted water) by a powerful electric discharge and the following water discharge under the extreme pressure of the vapor-ionic substance on the tail section of the water charge. The new forceful electric discharge drive is the major unit in the complex of highly effective and environmentally sound rock-destructing mechanism operating in the flow line mode when cavern excavations. Alongside, the article provides experimental design of a mud-pulse rock-destruction device is the current model of a new drilling tool for the large-diameter gasification wells sinking along the coal beds with the inclusion of a large number of rock formations with an impulse striking power of up to 25 kJ. The results of laboratory tests are provided. The received data and characteristics of the units and model parts operation will be used to create industrial samples of the new equipment. |
Key words | mud-pulse devices, rock solid destruction, electric discharge drive, flow line production, environmentally sound process |

Abstract | The article presents the results of investigations of complex processing of red mud obtained from high-alumina bauxites of alumina production by the smelting reduction method. Red mud is a production waste that contains useful components and can used as a complex raw material for the production of pig iron, rare earth element (REE) concentrates and titanium dioxide. Known methods of red mud processing by the smelting reduction method have not found application because of the impossibility of obtaining slag with low iron content. The urgency of the problem solved by the research is in the need of ways for red mud recycling. As a result, a method for processing the modified red mud by the smelting reduction was developed to produce cast iron and an oxide-free slag containing rare earth elements and titanium dioxide. The method consists in the preliminary treatment of red mud in a high-modulus alkaline solution at a temperature of 240-260 ° C with the addition of calcium oxide to the pulp from the calculation for obtaining a modified red mud – a hydrogarnete slurry those main compound is the ferrous garnet-3CaO ∙ Fe2O3 ∙ 2SiO2 ∙ 2H2O. Reducing melting of the hydrogarnete slurry has made it possible to produce cast iron, and after magnetic separation – a nonmagnetic slag fraction containing 0.22 % of iron, which determines the possibility of obtaining high-quality REE concentrates and titanium dioxide in hydrometallurgical processing. The extraction of iron into cast iron is 88.0 %, into the magnetic fraction – 11.9 %, into the non-magnetic fraction – 0.1 %. The extraction of titanium into the magnetic fraction was 34.3 %, and in the nonmagnetic fraction was 65.7 %. The recovery of REE into the nonmagnetic fraction was 65.7 %. |

Abstract | The principal technological scheme of desorption of gold and concomitant metal-impurities from the AM-2B resin phase used for the sorption processing of gold-bearing ores is considered. The proposed combined scheme, involving the use of two traditional, independent from each other methods (thiocyanate and acid-thiourea) for eluting gold, includes desorption of metal impurities from the resin with alkaline solutions of sodium thiocyanate, and gold with sulfuric acid solutions of thiourea. To shorten the duration of the process research of proposed technology was carried out the in a conical apparatus. The results of study of the elution of gold and impurity metals from anionite saturated with the following components, mg/g: Au – 2.6; Cu – 3.5; Zn – 1.3; Ni – 2.9; Co – 3.3, are given. It is shown that the main amount of impurity metals is desorbed from the resin upon its thiocyanate treatment, while the transition of gold into the eluate is negligible. The composition of the eluate in the thiocyanate treatment of saturated resin is, mg/l: Au – 1.7; Cu – 156.0; Zn – 53.0; Ni – 89.0; Co – 102.0. The subsequent treatment of the resin with sulfuric acid solutions of thiourea allows the conversion of 89.32 % of gold from the ion exchanger into the eluate. The resulting eluates containing ~113.0 mg/l gold and a small amount of impurities are target solutions for obtaining a valuable metal. The ion exchanger was regenerated by washing with water and treating with an alkaline solution of sodium to convert it to OH form, since gold sorption is carried out from alkaline cyanide solutions of heap leaching. Residual contents of components in the resin after regeneration were, mg/g: Au – 0.24; Cu – 0.23; Zn – 0.15; Ni – 0.07; Co – 1.29, which allows the successful use of the regenerated resin in the next stage of sorption. |

Abstract | The article describes results of research on copper recovery from low-grade copper ore by heap bioleaching method. The objects of investigation are ores of the Benkala deposit. Results of chemical analysis by atomic-emission spectrometric method and chemical phase analysis present ores element composition and identify copper and iron forms existing in the ores. Ores were subjected to bioleaching by chemolithotrophic bacteria, which oxidizes sulfur and iron compounds. Acidithiobacillus ferrooxidans FT-24 and BF, Acidithiobacillus thiooxidans BS, Acidithiobacillus ferrivorans SU-8 and Sulfobacillus thermosulfidooxidans ST-12 strains were used in the research. It was modeling the process of bacterial heap leaching of low-grade ore in percolation columns. Comparison of efficiency of sulfuric acid and bacterial leaching in percolation columns shows advantage of bioleaching. The copper yield was 47 % at using conventional sulfuric acid leaching, while utilizing bacterial leaching increased the copper recovery up to 86 % during 90 days of the experiment. The values of oxidation-reduction potential (ORP) at sulfuric acid and bacterial leaching of copper ore presented are in accordance with yield of copper. The values of ORP at standard sulfuric acid leaching are between 330-360 mV, at bacterial leaching more high and are 480-550 mV due to high content of ferric iron. During the extraction of copper, the effect of the organic reagent LIX 984N in concentrations 50 and 250 mg/L on the activity of microorganisms was studied. As a result, the extraction reagent has a little effect on the growth of microorganisms and the extraction of copper. Without adding the extraction reagent, the total copper recovery was about 83 %, while the addition of the extraction reagent with concentration 250 mg/L decreased it to 81 %. So using bioleaching technology allows deep processing of copper ore due to oxidation of copper sulfide minerals. |

Abstract | The article contains the vanadium-containing ores oxidation of the Balasauskandyk and Kurumsak deposits in Kazakhstan using pyro-metallurgical methods upon availability of alkali metal salts; and the influence of various effects (temperature, the sort and reagents consumption) on the vanadium react degree to a soluble form has been studied. This like reducing-oxidizing roasting upon availability of alkali metal salts may contribute to the vanadium react to a soluble form that will provide for a more complete recovery of vanadium in subsequent stages. Chemical testing of original vanadium-containing ores, semi-quantitative X-ray phase and spectral cinders analysis obtained after vanadium-containing ore roasting are provided. Roasting and vanadium-containing ores oxidation were carried out by different options: 1 – upon availability of calcined soda, 2 – upon availability of sodium chloride, 3 – upon availability of calcined soda and sodium chloride mixture in 700-850 ° C temperature range for 2 hours. As a result, after the complete carbon combustion in the ore SiO2 quartz content in the cinder reaches from 89 to 96% was found, also hematite Fe2O3 from 1 to 5.5%, specular stone (K,Ва)(Al,Fe,Mg,V)2(AlSi3O10)(OH)2 containing vanadium from |

Abstract | The purpose of this work is to determine the regularities of reducing the losses of valuable metals with waste slag of copper smelting in the conditions of the Balkhash copper smelter. The change in the raw material base, the introduction of low-quality copper concentrates in the Balkhash copper smelter (BCS) on the VF-1 and VF-2 (Vanyukov furnaces), are accompanied by the production of waste slag containing increased copper content, which requires additional technological operations for their depletion. Smelting in optimal conditions can exclude the organization of separate processing waste slag. Ways to improve the autogenous smelting of copper concentrates at BCS are the following: strict adjustment of the charge composition by basic metals and silicon dioxide, temperature regime, maintaining the heat balance with the possibility of using fuel, optimal operation of the electric mixer. A study of the dependences between the copper content in charge and slag on furnaces VF-1 and VF-2 of BCS allows establishing that the amount of slag increases 1.5-2 times with a decrease of the copper content in the charge 2 times. Reducing the copper content in the feed increases the losses of copper in the slag. The dependences of the copper content in waste slag on content of magnetite and zinc indicate that an increase of the magnetite content from 8 up to 11 % leads to an increase of the copper content in the slag for 0.4-0.5 %. An increase of the zinc content from 4 up to 6 % leads to increase for 0.3-0.5 % of copper content in the slag. Thermal studying of samples of dump slag, produced on furnaces VF-1 and VF-2 showed that the temperature of the slag at the outlet of the electric mixer should be at least 1300 °C. This temperature is difficult to reach by autogenous smelting regime. To solve the problem of complete separation of slag and matte, it is necessary to overheat slag for 70-80 0С, which will realise at electric energy consumption 80 kWt·h/t of slag and allows obtaining waste slag of the optimal composition. |

Abstract | This work is devoted to the investigation of the possibilities of processing oxidized copper ore and sulfide copper concentrate of the Aktogay deposit by pyrometallurgical methods at the operating metallurgical units of the largest copper producer in Kazakhstan, Kazakhmys Smelting Ltd. The chemical, phase compositions and thermal properties of the samples of the Aktogay ore and concentrate were investigated. To test the possibility of using oxidized copper ore of the Aktogay deposit as quartz flux for autogenous smelting in Vanyukov furnaces (VF) with copper sulphide concentrates laboratory experiments were carried out. They made it possible to establish that the replacement of quartz flux on the oxidized ore of the Aktogay deposit is entirely permissible in consideration of the satisfactory composition of slags and mattes obtained in the smelting, even when the content of silica in the ore is 64.56 %. With a higher content of silica in the ore, its use as a flux will be even more effective. The available capacities of the two Vanyukov furnaces are not sufficient for processing all available high-sulfur raw materials, including the Aktogay sulphide copper concentrate, using autogenous melting. Therefore, in the laboratory and in an industrial scale, a preliminary test was carried out on the possibility of processing a part of the copper poor and high-sulfur Aktogay concentrates on the electric furnaces of the Zhezkazgan Copper Smelting Plant (ZCS). The results of laboratory studies and preliminary industrial tests have shown the possibility of such processing with the production of mattes containing no less than 47 % of copper and suitable for converting on existing equipment of ZCS. |

Abstract | The review covers the methods for sorption recovery and concentration of rare-earth metals (REM) from solutions of extraction phosphoric acid (EPA). Sorption extraction of the REM seems most appropriate at the stage of primary concentration, but a significant amount of iron (III) and calcium as the most interfering impurities are the problem, both at the stage of sorption and at the stage of desorption. The results of studies on the sorption of trivalent ions of cerium, lanthanum and iron on sulfonic cation-exchange resin KU-2-8 and macroporous weakly acidic cation exchange Cybber CRX 300, are presented. It is established that the cation exchanger Cybber CRX 300 by exchange capacity for lanthanum and cerium and kinetic properties is inferior somewhat to sulfonic cation-exchange resin KU-2-8 at sorption from acidic solutions, but can be used to concentrate and separate the REM from iron. The review presents data of the pilot trials of the technology for extracting rare-earth metals from dihydrate extraction phosphoric acid (45 % P2O5) produced by «PhosAgro-Cherepovets» JSC (RU). The results of tests of sorbents TP260, Purolite S957 (Monophos), sulfonic cation-exchange resin РРС 160 and sorbent АА03 at sorption: from sulphate solution after decomposition of phosphate raw materials; from a solution of hydrolysis sulfuric acid after precipitation of titanium dioxide; from sulfuric acid solutions after sorption of uranium are presented. The distribution of rare-earth metals during their sorption by KU-2 sulfonic cation-exchange resin from solutions of phosphoric acid, as follows: dihydrate EPA partially evaporated 43.69 wt. % P2O5, «Balakovo Mineral Fertilizers» JSC; dihydrate EPA, without evaporation 26.09 wt. % P2O5, OJSC «Ammofos»; dihydrate EPA, evaporated 52.54 wt. % P2O5, «Ammofos» OJSC, was studied. The distribution coefficients of individual lanthanides are obtained. The analysis of literature data has shown that the choice of sorbent is the most difficult task when developing the technology for sorption extraction of REM from multicomponent solutions. |

Abstract | The need to involve the production wastes – ferrous sands of the Pavlodar aluminum plant into the processing is associated not only with environmental protection, but also with the necessity to increase alumina production, complex waste utilization and the sintering process normalization. For high-iron bauxites effective using in the early stage of the process, the maximum separation of ferriferous sands from bauxite is carried out. The waste flow of ferriferous sands is 50 t/h, which are 10 % from general flow of feed bauxite. It contains up to 60 % of iron oxide and 17 % of aluminum oxide, which is irretrievably lost, reducing the overall extraction of alumina from bauxite. To involve production wastes in the processing, detailed physicochemical studies of the composition of ferriferous sand by methods as follows: X-ray, optical, thermal, phase and chemical analyzes of the fractions from +1 to -0.15 mm were carried out. It is shown that with the decrease of the fraction, the content of iron oxides (56.3-60.9 %) increases, and the content of aluminum oxide decreases (13.4-10.4 %). X-ray analysis of the averaged sample showed that the main iron-containing components in the ferriferous sands are, %: hematite 29.1; hetite 8.6; magnetite 6.19; siderite 8.14; as well as pyrite and andradite – by 2.58. Aluminum-containing phases are, %: gibbsite 11.6; serpentine 8.94 and kaolinite 7. The composition also includes concomitants, %: quartz 5.8; calcite 8.49 and gypsum 3.7. The performed thermal analysis also confirmed the presence of identified phases. The decomposition and oxidation temperatures of the components that occur with increasing temperature were determined. The obtained data on the phase composition and its transformations are necessary when developing methods for the ferriferous sands utilization. An analysis of the physicochemical data of ferriferous sands’ composition has shown that they can be considered as a potential raw material for pigments and cast iron production. The development of new technical solutions aimed at the involvement of production wastes – ferriferous sands in the process will increase the profitability of the existing alumina production by low-quality high-iron bauxite processing. |

Abstract | The study of phase transformations in the system” lead-containing dust – sulfur ” is actual, as in many pyrometallurgical processes lead-containing dust is formed. The accumulation of such industrial waste causes ecologically stress on the environment. The sulfur is select as a sulfiding agent due to the problem of its utilization in the oil industry. The article covers the possibility of lead dust sulfiding with technical sulphur. Thermal and x-ray phase analysis of mixtures of lead dust and elemental sulfur in various ratios was carried out. Thermal analysis was performed on a Q-1000/D derivatives without air access, which was achieved by blocking crucible with the analyzed samples by aluminum oxide, in the temperature range 20-1000 ° C, heating mode – dynamic (dT/dt = 10 deg/min), reference substance – calcined Al2O3. X-ray diffraction analysis was performed on an automated diffractometer DRON-4 with CuКa-radiation and β-filter. In the studied system, the main temperature intervals, wherein sulfur actively reveal itself, are 60-220 and 220-360 °C. The state of the system beyond 450 °C is clear from the physical properties of the lead dust. Rising of sulfur concentration increases the visibility of the peak on the DTA-curve associated with polymorphic transformation of lead oxy-sulfates and activation of sulfide formation processes. The increase in the intensity of the effects of sulfur direct interaction with the components of the charge reflects the difference in sulfur concentrations in the compared samples. On the other hand, the increase of sulfur content in the composition of the sample leads to some attenuation of the physical properties (melting) of lead oxy-sulfates. Thus, the increase of the sulfur content in the charge more strongly stimulates the development of sulfidization process in the system, which takes place within 140-300 °C. Within the same next stage of thermal manifestation, sulfide formation in the system and activation of the lead compound interaction is directly related to sulfur. The scientific and practical significance of the investigation is in the possibility of the use of technical sulfur, waste oil industry for sulfiding lead dust. |

Abstract | The article covers the results of researches on thermodynamic modeling of ferroalloy and calcium carbide obtaining from basalts of deposit Dubersay. The software package HSC-5.1, based on the principle of Gibbs energy minimum uses in the study. The influence of temperature (from 500 to 2500 °C) and the amount of carbon (from 40 to 60 % of the basalt mass) in the basalt–Fe–nC system was determined. It has been established that iron silicides are formed at T ≥ 1300 °C, Si at T ≥ 1400 °C, CaSi and Al at T> 1700 °C and CaC2 – at T ≥ 1800 °C. An increase of the amount of carbon from 40 to 60 % allows rise the degree of distribution of Si in the alloy up to 94 %, calcium in CaCl2 – up to 62.3 %, aluminum – to alloy up to 93.9 %. An increase of the amount of carbon allows increase the silicon concentration in alloy up to 55 % (at 1800 °C), aluminum – up to 17 % (at 2000 °C) and calcium carbide capacity – up to 350 dm3/kg. The method of rototable planning of the second order allows find equations of regressions of the influence of temperature and amount of carbon on the equilibrium distribution of silicon, aluminum, and calcium between the ferroalloy and calcium carbide. On the basis of this equations were determined, that within the temperature range 1956-1996 °C from the Dubersay deposit basalt, the ferroalloy with a content of ΣSi and Al 60.8-65.4 % (including 12- 15 % Si) and calcium carbide with a capacity of 250-300 dm3/kg are formed. Wherein degree of recovery into the alloy for silicon is 91-91.4 % and for aluminum is 63-75.1 % and calcium – into CaC2 is 60-60.7 %. The resulting ferroalloy by the content of silicon and aluminum can be attributed to the complex ferroalloy – ferrosilicoaluminium, calcium carbide – to the industrial product of grade from 3 and up to the highest. |

Abstract | The innovative technology was proposed for conducting the process of the rice husk thermal treatment. The principle of this technology involves using the pyrolysis gas as the energy-generating fuel for the radiation heating of the plant raw material in the pyrolysis reactor. By calculation, it was proved that the warming-up of the rice husk with the heat from the pyrolysis gas burning was really feasible in the reactor with the internal diameter 1.5 m, length of the reactor 3.5 m, internal diameter of a radiant tube 0.5 m, and length of the radiant tube 4.0 m. The resulting excessive heat can used for domestic needs. The capability was determined to manage the operation mode of the pyrolysis installation increasing its efficiency through regulating the number of rotations and angle of the reactor’s incline. The appropriate process scheme for the rice husk treatment with production of silica-carbon was developed. It testifies that the produced silica-carbon represents a homogeneous mixture of carbon and silicon dioxide those were in the amorphous form. The presence of the component ingredients in the form of finely dispersed particles with the size of 10-50 nm provides homogeneousness of the material. According to its structure and features, the silica-carbon acts as a high-grade filling compound of elastomers and carbon constructional materials. The production cost of silica-carbon is 15-20 % less than the similar material obtained according to the pre-developed technology. Use of the radiation heating instead of the electric heating of the pyrolysis reactor allows reducing the operational costs. |

Abstract | The article gives an overview of Kazakhstan science and current provisions of the process of commercialization of scientific developments. The conclusions regarding the development of Kazakhstan science, in particular, the licensing mechanism, the problems of interaction between the integrations of industries and science, the need for marketing research as a tool for promoting scientific projects are examined. Initial conclusions were obtained regarding the stage of development of capital-intensive projects in Kazakhstan, the reasons for the current state of capital-intensive projects in Kazakhstan, including a weak marketing strategy and a shortage of qualified personnel. The problem of the lack of a proper regulatory, technical and scientific-methodological framework for ensuring the commercialization process is considered. Weak development of the regulatory and methodological framework does not allow to ensure uniform, systemic approaches to commercialization. In practice, each organization is forced to develop its own localized strategies, models, commercialization methods that are not adapted to the full range of existing market conditions, which adversely affects the competitiveness of scientific and technological developments of the Republic of Kazakhstan in the international arena. The results of studies of foreign and domestic scientists in the field of project management for the implementation of innovative products, its commercialization, materials of scientific and practical conferences, current legislative and regulatory documents in the field of commercialization of scientific developments are studied. The results of the research can be applied as an information basis for the commercialization of technology in scientific and educational institutions, in business, and in production. |
