Selective collector – polyfunctional (PF) reagent consisting of a mixture of butyl xanthate (BX), N-allyl-o-iso-butyl-thiono-carbamate (TC-1000) and composite aerofloat (CA) taken in a ratio of 1: 1: 2 was selected on the basis of comprehensive research. The colloid-chemical properties: surface tension, adsorption at the water-air line, wetting were studied for basic and polyfunctional reagents. Also colloid-chemical properties and flotation ability of sulfide mono-minerals: galena, pyrite, sphalerite, and chalcopyrite, with using of basic and multifunctional flotation reagents were evaluated. Furthermore flotation of sulfide polymetallic ore of Tishinsk deposit by using basic and PF flotoreagents was studied. It is shown that at collective lead-copper flotation by use of the mixture with optimum composition: PF reagent – 15 g/t; foamer T-80 – 10 g/t, was obtained copper-lead collective concentrate with content of a copper of 11.3 % at recovery of 80.4 %, with content of lead of 13.8 % at recovery of 73.0 %, with content of gold 13.3 g/t at recovery 41.4 %, with content of silver 144.8 g/t at recovery 45.78 %. In comparison with basic mode extraction of copper into the shared copper-lead concentrate increases by 4.1% and of lead – by 4.8%, content of Au and Ag increases by 2.9 и 20.4 g/t respectively. In case of zinc flotation with PF reagent concentration 55 g/t and foamer T-80 – 20 g/t zinc concentrate with zinc content of 56.3 % at recovery of 93.6 % was obtained. In comparison with the basic mode of zinc flotation (BX – 65 g/t, T-80 – 20 g/t) at PF reagent use the content of zinc in concentrate increases by 1.7 %; zinc extraction into zinc concentrate increases by 2.5%.

|Summary||The article covers the current state of the practice of concentration of chromium ores and their tailings. There are also presented the prospects of the development of the sector with taking into account modern trends. The aim of this study was to analyze the methods, used in the technology, its modes for chrome ores enrichment. It was studied their shortcomings and development prospects. In addition to practically used enrichment methods the research works dealt with the different ways of enrichment of chromite ores such as: hydrometallurgical processes, combined scheme with use of gravitational method were analyzed. The article covers the characteristics of the main types of ores, properties, and main demands to obtained products. It is noted that for large classes the gravity method – the enrichment in heavy liquids is more effective; for small classes – jigging, screw separation and enrichment on concentration tables. At the same time, the actual problem is the enrichment of small, thin and ultrathin classes, where the effectiveness of gravitational methods is low, due to which there are basic losses of valuable components from tailings. In the article the problem of technology for enrichment of poor chrome ore was discussed. The promising technology is the application of a combination of different methods: gravity, flotation, magnetic separation. Most of the investigation works take gravity method as basic first step, and magnetic separation or flotation processes as the final step for cleaning crude concentrate. In the review it is shown the main technologies for the processing of chromium ores, which are used both in the native (Kazakhstan, Russia) and foreign factories (Yugoslavia, Finland). The conclusion drawn from the review is that the challenge of processing thin grades of chrome ore is not completely solved. It remains urgent and requires further study.|

|Summary||The paper presents the results of research on the flotation enrichment of Zhezkazgan region’s oxidized copper ores with composition as follows, mass %: Cutotal. – 1.4; Cuoxidized – 1.2; SiO2 – 79.64; Al2O3 – 6.0; CaO – 0.88; Fe – 1.6; MgO – 0.66; Stotal. – 0.16. The enrichment includes pre-sulphidation by reagent prepared on the basis of mechanically activated sulfur and subsequent flotation. Processes of mechanical activation of elemental sulfur were investigated and the optimal shredding conditions were determined by the method of experiment planning. The sulphidation reagent with desired properties of sulfide-ion was obtained. Sulfiding properties of the reagent were studied on the oxidized copper ores and identified sulphidation conditions: temperature of the process 90 °C, sulfiding duration – 10 minutes, sulphidizer consumption – 100% of stoichiometrically required to transfer all oxidized copper into sulfide form. The influence of pre-sulphidation by the reagent on flotation of oxidized copper ore was investigated. Experiments were carried out under optimum conditions of flotation: the degree of ore sulphidation – 40 %; consumption of xanthate – 400g/t, of foaming agent – 100 g/t of ore. Also experiments on flotation without sulphidation of ore were carried out for comparison. It was found that pre-sulphidation of ore by reagent on the basis of mechanical activated sulfur has a positive effect on the results of flotation – the quality of the concentrate increased on 0.74 % and the recovery of copper into concentrate increases on 30 %. Mathematical models of processes of elemental sulfur mechanical activation, sulphidation and flotation of oxidized copper ore were obtained.|

The main factors: temperature, reducer and fluxing additive have the greatest influence on reducibility of ferrum and titanium oxides inside of titanium magnetite concentrate in the process of kilning. Sodium carbonate is the most commonly used as a flux. Various forms of carbonaceous reducing agent vary in crystallization degree of carbon, and the more similar the structure to the graphite structure, the worse reactive capacity of carbon: activation energy is higher and development degree of carbon interacting with its dioxide with formation of active reducing agent carbon oxide CO is lower. To study the influence of solid carbon reducing agent form on solid-phase regeneration of titanium magnetite concentrate, the thermogravimetric research of interaction of anthracite, metallurgical coke and special coke, produced from low ash gas coal of the Shubarkol field, with titanium magnetite concentrate of the Tymlai field was conducted. In the process of kilning in the range of temperatures 450-500 оС Fe3O4 is converted into γ-Fe2O3, and in the range of 500-600 оС hematite interacts with sodium carbonate with formation of NаFеO2. These reactions are common both for furnace charge with anthracite or metallurgical coke, and for furnace charge with special coke. Regeneration of titano-ferrite included as a compound of titanium magnetite concentrate, is accompanied by metallic iron formation, and free titanium reacts with sodium carbonate and forms sodium titanium oxide melted at 1020-1055 оС, and ferrous titanate FeO×2TiO2 formation is possible at the temperature above 1200 оС. The thermogram of furnace charge, which includes special coke, notably varies from the thermogram of furnace charge both with anthracite, and with metallurgical coke. Thermoeffects characterizing formation of easily reusable sodium ferrite, disrupting of titano-ferrite with wustite formation, which regenerates to metallic iron and sodium titanium oxide, are displaced to the range of lower temperatures. Produced sinter is more incoherent, than in the case of application of metallurgical coke or anthracite. The study results of reducibility of titanium magnetite concentrate with anthracite, metallurgical coke and special coke, produced from low-ash gas coal, showed, that special coke has substantially greater reactive capacity in comparison with anthracite and metallurgical coke.

|Summary||This work aims to develop cost-effective technology for processing of low-grade zinc concentrate to produce zinc oxide, which has advantages over the industrially implemented technology for producing metallic zinc. Firstly, it is higher price of the resulting zinc oxide compared to the price of zinc metal. Secondly, it is the exception of technology the capital-intensive and expensive process – electrolysis of zinc. In the pre-cleaned from impurities zinc sulphate solution from the autoclave leaching of low-grade zinc concentrate of Nikolaev deposit of Kazakhstan the zinc content was representative (247,48 g/dm3). The study examined two options of experimental investigations of hydrometallurgical method of sedimentation of zinc oxide from this zinc sulphate solution and the more acceptable was chosen. The studies determined the optimal technological parameters of the 3 stages of hydrometallurgical method of sedimentation of zinc oxide from the studied solutions, providing the commercial production of zinc oxide. At 1st stage, the solution of zinc sulfate cleared from impurity was neutralized by a solution of ammonia NH4OH with obtaining complex salt Zn(OH)2∙ZnSO4 at 40 0С during 30 minutes; then the filtration and washing of a sediment by cation-polished water in the ratio L:S=7:1 and drying of a sediment at temperature 150 0С during 120 minutes are carried out.

The paper describes results of experimental determination of basic technology parameters of charge preparation for direct iron recovery. The charge consists of Sokolovsko-Sarbajsk ore Mining and Dressing Enterprise (SSOMDE) iron concentrate and carbon reductants: blast-furnace coke, charcoal and carbonizate recsil. SSOMDE concentrate consists mainly of magnetite and contains, %: Fe – 66.51; FeO – 22.63; Fe2O3 – 69.90; SiO2 – 5.05; А12O3 – 1.70; CaO – 3.47; MgO – 0.78; S – 0.32; Р – 0.05. Reductants chemical composition is as follows, %: blast-furnace coke: Fetotal – 0.76; FeO – 0.05; Fe2O3 – 1.04; SiO2 – 6.05; А12O3- – 2.62; CaO – 0.41; MgO – 0.46; S – 0.82; Р – 0.01; Csolid – 88.02; charcoal: Fetotal – 0.58; FeO – absent; Fe2O3 – 0.83; SiO2 – 0.10; А12O3 – 0.05; CaO – 0.73; MgO – 0.29; S – 0.02; Р – 0.09; Csolid – 79.85; and carbonizate recsil: Fe – 0.28; FeO – absent; Fe2O3 -0.40; SiO2 – 1.56; А12O3 – 1.04; CaO – 0.27; MgO – 0.32; S – 0.34; Р – 0.02; Csolid – 94.84. Calculation of initial charge composition was made by the method of Yu. Yusfin and N. Pashkov. It was found that the charge for ore-carbon pellets should contain 83.78 % of SSOMDE concentrate and 16.22 % of blast-furnace coke; 82.39 % of SSOMDE concentrate and 17.61 % of charcoal; 84.78 % of SSOMDE concentrate and 15.22 % of carbonizate recsil. Differential-thermal analysis was used to find the temperature of initial interaction of SSOMDE magnetite concentrate with carbon reductants. It was found that active recovery of iron begins at the following temperatures: blast furnace coke 930 °C, charcoal 780 °C, carbonizate recsil 840 °C. Ore-carbon pellets metallization experiments in Tamman resistance furnace (as binder – liquid glass, ρ = 1.20 g/sm3) show that recsil allows getting highest degree of metallization about 83 – 90 %. Metallized with recsil pellets contained 55 – 60 % of metal iron.

Production experience shows that use of many types of secondary mineral resources is technically feasible and efficient. One of the resource in the production of non-ferrous metals is use of waste of iron and steel industry, in which the content of non-ferrous metals up to industrial conditions. Thus, in dusts of gas purification of some plants of ferrous metallurgy the zinc content reaches 15 %. The results of the study of the binder agent effect during the briquetting of charge, the type of the carbonaceous reducing agent, the consumption of reducing agent, fineness of charge components on the process of carbothermal reduction of zinc from oxidized zinc ore with the addition of stale dust of gas cleaning of blast furnace smelting were presented. Bentonite, hydrated lime and treacle were tested as binding agent for briquetting of charge. It is established that optimum binding agent is treacle in an amount of 4.5-5.0 % by weight of the weight of the ore. It is shown that the residual zinc content in a product of the reduction roasting when using the special coke obtained from coal of Shubarkol deposit is 1.9 times less, than at using anthracite and 3.3 times less, than at using metallurgical coke, i.e. special coke is the most active reducing agent. The carbon consumption during carbothermal reduction of zinc from oxide ore with the addition of dust is 22-24 % lower than in case of zinc recovery from ore. It was found that crushing of charge to class +0.071-0.04 microns reduces the degree of zinc sublimation. If the size of charge is +1.0 microns, the residual zinc content in the cinder is increased. High recovery efficiency is achieved with the following composition of charge, wt. %: oxidized zinc ore – 53.8; dust of gas purification of blast furnace smelting – 26.9; special coke – 21.0; treacle – 5.3.

|Summary||Grinding and flotation theories still have not a generalized expression. In this article, the authors developed a method for integrated studying of the processes of grinding and flotation in the frame of single mathematical model with using probabilistic theory of grinding in ball mills based on probabilistic and deterministic planning of experiment. Partial and generalized dependences of copper content and recovery into the concentrate of the basic flotation from the grinding duration, from consumption of xanthate and from the duration of flotation were obtained. By using the calculations of fractional composition on the basis of the probabilistic model of grinding it was explained the extreme nature of the dependencies of copper content and extracting on the duration of grinding due to increasing of the output of slimy fractions, resulting in a decrease of the yield of the desired fraction. Multifactor model of the process has been obtained and based on it the matrix-nomogram was calculated, which can be used as a technological sheet with the accentuation of the zone of optimal modes of grinding and flotation processes.|

|Summary||The analysis of published data of dissociation of mercury selenide on metal and chalcogen shows a lack of consensus on the forms of mercury presence in vapor phase over its selenide, although the majority of researchers consider decomposition process of chalcogenide and mercury transition to the vapor phase as a primary one. In this respect, the applied method of the designed partial pressure diagrams with the reference constants applied, allows to determine thermodynamically stable phases of mercury-selenium system for the distillation refining conditions of chalcogen at the temperature interval 400-672 °C, and the pressures 1.3·10-5 0.1 MPa, whereas, gas phase is represented by vaporous selenium. Due to the thermodynamic study of mercury selenide dissociation in conditions of distillation recovery and selenium refinement, the partial pressure diagram is designed in coordinates Т-1 – lnpSe(г) – lnpHg(г). On the basis of this diagram with lower partial pressures of mercury vapor, the elemental mercury is indicated as thermally stable phase over its selenide, and at considerable partial pressures of mercury vapor, mercury selenide occurs as the stable phase in vapor. An increasing partial pressure of mercury vapor reduces a region of thermal stability of mercury selenide. Equilibrium region between gaseous mercury and its crystalline selenide is degenerated at boiling point of selenium. At the partial mercury vapor pressure equaled to atmospheric, the field of the selenite existence is degenerated as well. In a process of the selenium distillation separation from mercury impurity in vacuum at its lower content in the initial one and respectively lower partial pressure of mercury vapor, the chalcogenide decomposition into vaporous metal and chalcogen takes place.|

In the paper we discuss the theoretical possibility of improved fluorine technology application for recycling barium-containing wastes produced at flotation concentration of complicated by mineral composition barium-polymetallic ore. The waste contains, %: up to 37 barium; 0.3 rare metals; over 1 total copper, lead and zinc. The technology suggests combined use of bi-fluoride and ammonium sulfate for the removal of silicon dioxide and transformation of majority of raw material components into sulfate form at 473–673 К. In general, theoretical possibility of fluorine-ammonium sulfate method application is based on results of thermodynamic analysis of waste components interaction with bi-fluoride and ammonium sulfate within 298,15–800 К. Temperature dependences of Gibbs energy for the reactions of fluorination and sulfation of barium wastes’ components were obtained in the process. It was found that at 298.15-800 К the probability of fluorination of the components, except barium sulfate, titanium oxide and copper sulfate, is sufficiently high. Sequence of the substances interaction with fluoridizer is determined as follows row: BaO, Y2O3, Sc2O3, Li2O, Al2O3, CaO, Ga2O3, MgO, V2O3, PbO, Fe2O3, ZrO2, ZnO, CuO, TiO2, PbS, ZnS, BaSO4, CuS, beginning from highest interaction probability. It was found that at 298.15-800 К the probability of the components sulfation, except silicon and copper sulfide, is sufficiently high. Sequence of substances interaction with sulfatizing reagent is determined as follows row: TiF4, ZrF4, VF3, BaF2, PbF2, FeF3, CuF2, ZnF2, LiF, CaF2, YF3, GaF3, MgF2, AlF3, ScF3, beginning from highest interaction probability. The conclusion was made that sintering with combined use of bi-fluoride and ammonium sulfate gives possibility for processing of barium waste with its components transformation into sulfate form, except copper sulfide.

|Summary||In production of steel by LD – process a significant amount of ferriferous dust which is caught then in systems of wet purification of flue gases is formed. The sludge emitted at the same time is a major source of raw materials for the production of cast iron and steel because of content in it a large amount of iron. It is also characterized by the increased content of zinc. Recycling of this waste solves the problem of natural resources saving and significantly reduce environmental load. The main objective at recycling of sludge is decrease the content of zinc in them to the acceptable indicators (less than 0,5 %). Results of the research of process of dezincing the sludge by hydrometallurgical method – leaching of zinc from the sludge by solutions of hydrochloric acid are presented in the article. An object of the research was the BOF sludge which contains 1,24 % of zinc. The leaching was carried out in the laboratory conditions at the room temperature. Based on the experimental data, the optimal conditions were determined for leaching the sludge: hydrochloric acid concentration – 15%, process duration – 90 min., the phase’s ratio of liquid : solid = 6:1. Allocated at the same time iron cake contains 0,43 % of zinc and it can be returned in production cycle at a stage of agglomeration of iron ore raw materials.|

|Summary||Based on the analysis of technology for processing of uranium-containing raw materials, potential sources of rare earth elements were identified among the industrial products and waste: uranium sorption tailings, sulfuric acid solutions of heap leaching of uranium, industrial waste mineral formations from uranium phosphate ores processing. Comprehensive study of processes of sulfuric mother liquors after uranium ores heap leaching cleaning from iron, extraction REE (rare earth elements) by methods of adsorption and extraction allowed to offer technology for producing from them the concentrate, which includes the partial precipitation of ferric alkali and reduction the remaining sodium sulfite, sorption and extraction concentration of REE, drying and calcination of precipitate at 500 0C. The resulting concentrate is the sum of REE oxides with admixture of oxides of aluminum and iron. At low initial content of REE in solution of heap leaching and absence of selective sorbents, through their recovery is small. So, more preferable is use as a raw material source of industrial waste mineral formations (IWMF) from phosphate uranium ore processing, the content of REE in which reaches up to 5.0 %. Studies paid considerable attention to opening the IWMF by acidic and alkaline methods, each of them was estimated. The optimum conditions for IWMF leaching in two stages were determined. Data on extraction recovery of REE sum with obtain the concentrate were presented. The possibility of phosphorus isolation as a separate product was shown. Based on these results flow-sheet was offered for extracting REE into the concentrate containing over 60% rare earth oxides from IWMF after processing of phosphate uranium ores. Sorption tails, from a technological point of view and by the chemical composition are difficult raw material. Practice has shown that the extraction of REE from them is unrewarding.|

|Summary||Research and development of new more selective reagents-collectors for improvement of flotation process efficiency represent one of the main priorities in the development of innovative technologies pertaining to flotation separation of various substances and minerals. The use of collectors’ mixtures is being considered as the universal instrument for ensuring necessary proportion in every individual case with respect to the amounts of chemically and physically sorbed collecting reagents on the surface of floatable minerals. Currently hard-dressed, refractory ores and secondary raw materials, which characterized by the low content of valuable components, fine dissemination of mineral assemblages and similar technological properties of minerals constituent are widely involved in the recycling processes. The possibility of processing tailings after flotation beneficiation was studied by using as example tailings of the Zhezkazgan benefication plant and the Tishinsk copper ore deposit with application of the modified multifunctional flotation reagents. Modified polyfunctional collector is the mixture of composite airfloat, TC-1000 and butyl xanthate. Reactants ratio is 1:1:3. The advantage of the suggested flotation reagents is that they are composed of two polar groups and have a long hydrocarbon radical. This structure being in the water during flotation process plays a dual role: first, as a collector adsorbing on the mineral surface it produces metal complexes with polar groups in the form of bridges, second, apolar radicals flocculate valuable slimed components, thereby intensifying flotation process. It was shown that flotation of Zhezkazgan tailings with application of the lesser modified reagent amount compared to butyl xanthate has enabled to produce crude copper concentrate with 13.0 % copper content and 80.22 % recovery degree. Compared to the baseline technology copper content in crude concentrate increased by 5.1 %, recovery degree – by 31.4 %. In case of Tishinsk tailings’ flotation copper recovery into the collective concentrate increased by 2.14 %, zinc – by 8.64 %, Fe – by 4.56 %, gold – by 5.5 %.|
