Overview

Lobash-1 Deposit is a complex object (quartz-sulfide stockwork contains gold, copper, silver, bismuth, molybdenum, osmium, etc.). The main evaluation of the Deposit is carried out in the format of conventional gold (AI+Cu). Copper (si) was translated into conditional gold (Au-usl.) with a conversion factor of 2,878. With this in mind, the production technology was selected. As a result of the work (in accordance with the agreements concluded with Federal Government Menedgment Enterprise «Central Scientific Research Geological Prospecting Institute» and Moscow representative office "ALIUD" GMBH), the most acceptable for the ore Deposit Lobash-1 recognized flotation technology. As a result of ore flotation according to the selective scheme, the content in the copper concentrate is: - gold 35.57 g/t, -silver -174.33 g / t, -copper-15.3 %. According to the simplified technological scheme with the production of one commodity product, a conditioned gold-copper concentrate suitable for processing by pyrometallurgical technology at existing enterprises, the extraction of metals is: gold 75.5%, copper 83.7%, silver 70.3%. Currently, in accordance with the license agreement, the technical project of experimental and industrial development of the field (Rosnedra ЦКР-ТПИ Protocol No. 177/13-STP dated 24.12.2013) is approved, according to which it is planned to pilot development of the field (in the amount of 10 thousand tons of ore), with the selection of a large-scale sample.
