The article presents the results of a study of the qualitative and quantitative analysis of metal ions in the bacterial oxidation of flotation concentrate in the liquid phase by mass spectroscopy. Changes in the concentration of metal ions (Na, Si, K, Ca, Fe, etc.) and ions of noble metals (gold, silver) in the process of bacterial oxidation of flotation concentrate were determined and changes in their concentration in the process were substantiated

The article presents the results of microwave processing of gold-containing sulfidic carbonaceous flotation concentrate, with the aim to oxidize sulfide minerals and organic carbon, in which gold is associated. The flotation concentrate was processed in a microwave oven with an output power of 700 W, so that after every 2 minutes of treatment the magnetron was turned off, the sample was mixed, then turned on. The degree of removal of sulfide sulfur was 96%. Organic carbon is removed by 76.7%. The IR spectra of the initial flotation concentrate and microwave treatment product are given, as well as the results of …

he article describes the history of the development of a new type of analysis of geological samples for gamma-activated gold method. The Central Mining Administration of the Navoi Mining and Metallurgical Combine announces the creation of a gamma-activated analytical laboratory at the Muruntau deposit. The prospect of gamma-activated analysis of gold, silver and rare metals in Uzbekistan and around the world.
Analysis Of Ash Fireplant Slates Of Deposit Sangruntau And The Possibility Of Their Enrichment, K.S. Sanakulov, O.F. Petukhov, B.T. Ruziev, U.Z. Sharafutdinov

This article provides laboratory research data on the analysis of the ash of combustible shale from the Sangruntau deposit and the possibility of their enrichment. Magnetic enrichment of the ash of combustible shale was carried out in order to determine the yield of the magnetic fraction, determine the chemical composition of the products of magnetic separation, determine the extraction and the enrichment factor for the main elements. When gravitational enrichment of the ash of combustible shale gold almost completely goes into the gravity concentrate. Gravitational enrichment of rhenium, vanadium, copper, zinc, uranium does not occur.
