Abstract
The review of copper ore processing flow charts in application at ore mills in Russia and abroad is presented. The scope of the analysis embraced the reagent regimes and flotation performance. Brief information about collecting agents, frothers and depressants is given. The influence of actuation medium in flotation of copper-nickel ore is studied in terms of bulk copper-nickel concentration. The tests were carried out with production of a rougher concentrate in the acid and alkaline media with its further scavenging.
