  • mining nahs in pper flotation - Ankersmid Group

    Flotation has been used in mining for over 150 years to enrich the copper content of crude ores from around 1% to approximately 30%. During flotation, the finely ground ore is mixed with water. The addition of chemicals makes the ore particles differentially wettable; valuable substances are extracted while worthless particles are left behind.

  • Effect of grinding media and NaHS on copper

    2000-11-1  The copper mineralisation in the ore sample examined was predominantly bornite (CusFeS4), a secondary copper mineral known to oxidise readily (Buckley et al., 1985) and minor chalcopyrite (CuFeS2). Various hypotheses have been proposed concerning the improvement in copper flotation in the presence of NariS.
