1. Describe current state of processing of mineral resources of Kazakhstan.

Kazakhstan - the world's largest producer of beryllium (1-4 seats), niobium, gallium, technical thallium, titanium sponge (3rd place), rhenium (1-5 seats), uranium (7th place), coal and silver (9th place) zinc and alumina (10th place). We have concentrated 45% of proven reserves of uranium. In reserves of tantalum, niobium Republic is ranked 1st among the CIS countries.

The reduction in the production capacity of the mining industry (except oil and gas) of the CIS countries is not due to an excess of production, and with the lack of demand in the domestic and low competitiveness on foreign markets. The main reasons for the reduction in outputs are aging funds (ferrous and nonferrous metallurgy of Kazakhstan, respectively, 36.8 and 41.5%), a significant reduction in recent years of investment in these sectors. The current state of the mining industry in Kazakhstan is characterized by a backlog of development of mineral resources base, the lack of significant capital investment in the sector, the deterioration of geological and mining conditions of field development. The increase in production and processing is possible only through the development of new deposits and the involvement of the complex testing of off-balance ores, dumps and tailings re-pillar mining. To date, the country has accumulated more than 20 billion tons of industrial waste, including waste of man-made (off-balance ore dumps, tailings), non-ferrous metallurgy is 10.1 billion tons, and black -8.7 billion tonnes. In the period mining ore deposits in Rudny Altai now accumulated 360 million tons of solid waste of mining and metallurgical production, which contain about 2 million tons of copper, lead, zinc and approximately 120-130 tonnes of gold. The low level of utilization of solid waste in the country due to lack of:

• Equipment for the processing of many types of wastes and their preparation for processing at the enterprises of other industries;

• economically reasonable methods of calculating the efficiency of waste management, taking into account environmental requirements, as well as economic incentives for companies;

• timely information on volumes of waste, their physicochemical properties and methods of use.

Inventory of waste mining and metallurgical complex would provide a more complete and accurate information for the analysis of their impact on the ecological environment.

To involve technogenic waste in material production is necessary for them to establish a specific list of requirements to identify the relationship between the properties of the waste, their possible areas of use and necessary for their preparation and processing technologies and equipment. Efficiency of the waste must be greater than that of primary production.

2. Specify main minerals and ores of rare metals and their methods of enrichment in Kazakhstan.

Main minerals and ores in KZ: wolframite (Fe,Mn,Mg)WO₄, molybdenite MoS₂, tantalite (Nb, Ta,Ti)₂O₆, beryl Al₂[Be₃(Si₆O₁₆)], spodumene LiAl[Si₂O₆]. We know other groups of minerals of rare elements (sulphates, hydroxides, phosphates).

Element	Minerals and ores
Rhenium	Molybdenite, bornite, chalcopyrite
Gallium	Bornite, chalcopyrite, enargite, germanite
Germanium	Bornite, sphalerite, chalcopyrite, enargite, tetrahedrite, sulvanite
Thallium	Galenite, colloformic pyrite, molybdenite
Selenium	chalcopyrite, galenite, arsenopyrite, gray ores, molybdenite
Tellurium	Native gold, bismuthine, galena, chalcopyrite, pyrite

Вecause of the small concentration of rare metals in the ore are important processes of ore enrichment and concentration of rare elements in the processing of raw materials.

None of rare metal is not reduced directly from the raw ore. Previously, pure chemical compounds (oxides, salts), serving raw material for the production of pure metal, are obtained from raw material

Main peculiarities are primary enrichment (after grinding to the optimal size corresponded to average grain size of rare metal minerals) with gravity methods using jigging machines, spiral separators and concentration tables, final processing of gravity concentrates using magnetic and electrical separation.
