RESULTS OF SCIENTIFIC RESEARCHES

Over the past 5 years, the laboratory has conducted research in the framework of 4 state budget and 25 contract projects.

1. Within the framework of the project “Development of rational technologies for processing complex ores of deposits and manifestations of Uzbekistan”, technological studies of tungsten-containing ores of the Khodzhadyk deposit and tungsten-containing wastes of the tailing dump No. 1 of the Ingichka concentrator were carried out and recommended schemes were developed.

2. Within the framework of the project “Development of rational technologies for processing ores and dumps of developed deposits in Uzbekistan”, effective technological schemes for processing gold-bearing ores of deep horizons of the Muruntau, Gujumsay, Charmitan deposits, off-balance ores of the Kokpatas and Daugiztau mines have been developed.

3. Within the framework of the project “Studying the forms of finding useful components and developing a technological scheme for processing precious metal and polymetallic ores from deposits prepared for industrial development”, technological studies were carried out and optimal schemes for processing gold-bearing ores from the Tuyachavul and Kokpatas deposits were developed.

4. Within the framework of the project “Development of effective technological schemes for processing ore minerals of the Republic of Uzbekistan using modern technologies and analytical equipment”, studies are being carried out to conduct technological studies of gold-bearing ores at sites and manifestations of Cholcharatau, Lolazor, Kumbogut, Bayram and Karatagat.

5. On the basis of the agreement, over the past 5 years, technological research has been carried out to study the ores of the Akba, Besapantau, Jasaul, Northern Daugyztau, Taskazgan, Tashkan, Oltin Diyor, Yangidavon, Yuzhny-1, Tuyachavul, Miskan, Nizhnekenzhasai, Tebinbulak, Amantaytau, Kalmakyr deposits , Marjanbulak and other objects.

In addition, within the framework of the roadmaps for the development of geological science between SE “IMR” and the Almalyk and Navoi mining and metallurgical combines, studies were carried out on the objects of the Angren mine administration, polymetallic ores of the Khandiza and Chinarsai deposits, the production of associated tungsten concentrate from waste processing GMZ-2, stubborn carbonaceous gold-bearing ores of the Karakutan, Ajibugut, Umid and Amantaytau deposits and completed with positive results.

In addition, in 2022, an innovative project was successfully completed as part of the state program for scientific activities of the Ministry of Innovative Development of the Republic of Uzbekistan.As a result, a technology was developed for obtaining high-quality graphite concentrate with an ash content of 0.74% from graphite ores of the Taskazgan deposit.
