Abstract
The main valuable component of disseminated ores of Norilsk-1 deposit is precious PGMs, gold and silver. In recent years, the disseminated ore beneficiation technology used at the Norilsk Concentrator of the Polar Division of MMC Norilsk Nickel has undergone changes to improve the recovery of precious metals. A direct selective flotation scheme was developed for cuprous ores. In addition, research was conducted, fundamentally new technologies were developed, and processing of some accumulated, previously stockpiled technogenic sources was started.
