COMPARISON OF CYANIDE AND THIOSULPHATE …

Many minerals have a detrimental effect on gold leaching. These minerals may dissolve in alkaline cyanide or thiosulphate solution and consume reagent and oxygen. Certain sulfide minerals are characteristically associated with gold, and the most important are pyrite, chalcopyrite, pyrrhotite, galena and arsenopyrite (Habashi, 1999).

Effects of CO2 on the zeta potential of hematite ...

Abstract Zeta potential is an important factor in affecting filtration rates of iron ore slurries. Two methods of zeta potential control investigated during this study were (1) pH adjustments and (2) surface modifications by reagent addition. It was originally hypothesized that adding CO 2 to a hematite slurry, would form a carbonic acid, leading to lower pH levels, lower zeta potentials and ...
