Abstract
The general regularities of gold mining in Russia are considered. Preliminary economic calculations of the efficiency of applying new technologies of extracting gold from refractory gold-sulfide ores of the Olimpiada deposit based on biohydrometallurgical production methods are given. This method will make it possible to extract 7.5 t of gold annually from unoxidized primary ores, which, taking into account the withholding taxes, will increase the company's profit by USD 20.5 mln. Options for the most complete use of complex ash-antimony-antimony ores were considered, which can provide additional economic benefit through the integrated use of raw materials: obtaining commercial antimony and sulfuric acid.
