Abstract
The procedures aimed to recycle off-test products of the dust-and-gas phase when producing copper at the industrial complex “Severonikel” of “Kolskaya GMK” JSC have been developed. Introduction of the proposed procedures into production will allow substantial reducing the environmental impact from cathode copper manufacture thanks to decrease of the gas phase dust content and exclusion of off-test products from the technological cycle. The advantages of the proposed procedures are low capital expenditures during implementation, increase in complexity of raw material usage, and fitness of the recycling procedures to the main technology of cathode copper manufacture.
