Sequential flotation is employed to process massive sulfide ore from the Noril'sk-Talnakh deposit in Russia and produce separate copper, nickel and pyrrhotite concentrates (Bulatovic Citation 2007; Kozyrev et al. Citation 2002); the pyrrhotite concentrate has a high concentration of Ni, Cu and PGMs and is processed further in a …
The ores of sulfide copper-nickel, copper-pyrite deposits, and ores of copper sandstones and slates are primarily pro-cessed abroad. The amount of copper in copper sand …
