RESULTS OF SCIENTIFIC RESEARCHES

Over the past 5 years, the laboratory has conducted research within the framework of 5 state budget and more than 100 contractual projects.

- As a result of the studies carried out on samples of quartz sand from the Kokayaz manifestation, a technological scheme for deep enrichment of quartz sands was developed to obtain a quartz concentrate with a content of 99,06% quartz, 0,02% iron oxide and less than 0,1% alumina. The resulting concentrate meets the requirements of the industry;

- As a result of laboratory technological studies in a sample of leucocratic granites, manifestations Kattasay-1 obtained feldspar concentrate containing the amount of sodium oxide and potassium 12,15% and iron 0,26%. The resulting product meets the requirements of the relevant standards;

- As a result of laboratory technological studies, phosphate concentrates containing 32,35 and 24,1% P2O5 were obtained in a sample of phosphorites from the Agitma occurrence. The resulting concentrates meet the requirements of industrial requirements;

- When enriching the barite of the Kushkumbay occurrence, a combined concentrate was obtained, which the content of barite reaches 84,6%, with its extraction of 89,6% of the ore. The resulting concentrate meets the requirements of the industry;

- As a result of the enrichment of wollastonite from the occurrence of Beltau, a wollastonite concentrate was obtained with a content of 95,4% wollastonite in it with an extraction of 73,8%. The resulting concentrate can be used for the production of porcelain, ceramics and colored paints;

- As a result of laboratory technological studies in a sample of talc from the Chettik manifestation, a concentrate was obtained containing talc 89,3% and iron 0,96%, with the extraction of talc 67,4%. The resulting talc concentrate meets the requirements of the industry;

- As a result of the enrichment of the vein quartz of the Ermamat manifestation, a quartz concentrate containing 98,9% silicon oxide was obtained using a combined scheme, with its extraction of 78,1%. The concentrate, which contains harmful impurities of iron and aluminum oxides, contains 0,01% and 0,4%, respectively. The resulting concentrate meets the requirements of the glass industry;

- When enriching a sample of serpentinite according to a combined scheme (gravity and electromagnetic separation), a magnesium-containing product was obtained with a content of 49,58% magnesium oxide with its extraction of 72,9%. In order to obtain a product suitable for the production of magnesia refractory material, pyro-hydrometallurgical studies were carried out. As a result of the technological research carried out, a magnesium-containing concentrate with a content of MgO–86,18% and Fe2O3 – 0,1%. The resulting concentrate meets the requirements of the industry;

- The resulting calcined dolomites at temperatures above 900 ° C meet the requirements of the industry and are suitable for use as a raw material for the repair and filling of steel furnaces. In addition, as a result of pyro-hydrometallurgical research, a magnesium-containing product was obtained, with a MgO content of 67.43%, corresponding to the technical characteristics for the production of electrical periclase powders and refractories;

- As a result of the enrichment of the talc sample from the Qizilsoy manifestation according to the recommended combined scheme, a concentrate was obtained containing 90,6% talc with an extraction of talc of 81%. The resulting talc concentrate meets the requirements of industry.
