Аннотация

Subjects of research: silver- and gold ore deposits of Almalyk-Angren ore area and accompanying them platinum and platinoids in fine admixture. Purpose of work: studying of silver- and gold ore deposits of Almalyk-Angren ore area for platinum-bearing. Methods of research: mineralogical, geochemical, crystallomorphological, as well as mass spectrometer, electron probe, atomic adsorption. The results obtained and their novelty: for silver and gold deposits it is established accompanying platinum-bearing. Forms of platinum and platinoids are mainly in fine admixture. Total content of platinum and platinoids is from less than 1 to 2,5-3 ppm and more (on the average 1,10 ppm). Relatively high content is typical for Pd, «light» platinoids (Pd, Rh) and platinum prevail. It is revealed earlier unknown precious metal (Au, Pd, Rh) type of exogenetic mineralization for the Yusuptash area. Practical value: mineralogical-geochemical research ofAg- and Au deposits increases a practical importance of their nontraditional platinum-bearing. The materials of researches can be used for perfection of technology of frill extraction of useful components and as an additional source of reception of platinum and platinoids at a complex working off of ores. Degree of embed and economic effectivity: results of research are transferred in the form of the report to the State Committee on Geology and Mineral Resources of the Republic of Uzbekistan (ref. № 65 from 26.06.2008) with a priority of authorship of opening of precious metal mineralization that was unknown (perspective) before. Scientific and practical results are introduced to Open Society «Sharqiy Qurama» (the certificate about acceptance to use from 03.08.2009), the Tashkent chemical-technological institute (TCTI) to the chair of «Analytical chemistry and technology of precious metals» (the certificate of introduction from 27.01.2010), Open Society «Uzbekugol» (the acceptance certificate on introduction from 09.02.2009), SE «Geological museum» of State Committee on Geology and Mineral Resources of the Republic of Uzbekistan (an extract from the report on reception to introduction and use №4 from 09.06.2008 and the certificate of introduction from 12.01.2009). The part of materials of work and the methodical manual of the author «Typomorphism and crystallomorphological analysis of pyrites» is used on the lectures and practical trainings at the Geology faculty of NUUz and TCTI. Field of application: the perfection of the technology of useful components’ extraction and additional reception of platinum and platinoids.
