copper flotation 2007 copper flotation and leaching

Dec 01, 2011· Incopperrecovery from combinedflotationconcentrate and smelter dust, further complexities may probably arise when different minerals are galvanically coupled (Petersen and David,2007). The difference between the rest potentials of both minerals (primary sulphides like chalcopyrite and secondary ones like chalcocite, covellite, and bornite ...

    Aug 01, 2020· 1. Introduction.Copperis one of Australia's top commodity exports, hosting the world's largest iron oxide‑copper‑gold (IOCG) deposits. However, uranium and its radioactive decay radionuclides are enriched in IOCG ores due to a strong association of uraninite (UO 2) with Cu Fe sulphides and iron oxide (hematite, Fe 2 O 3), which are impurities in thecopper flotationconcentrate.
