Abstract

Results of research of substantial and technological characteristics of gold — bearing ores are presented in the article. It was revealed that ores are refractory for the “basic” technology processing; gold extraction is less than 34% for “sorption cyanidation” technology. Research based on intensification of ore-preparation processes (application of chemical agents on milling stage and addition of oxidizing agents on cyanidation stage) was carried out for gold losses decrease. Indicators of processing of ore with the medium sorption activity are given for two directions: sequential floatation of carbon - containing substance and sulfides and sorptive leaching with the application of active coal.

Research was carried out в within the framework of the program « 42P « Far East»: project 12-I-R27-03.
