Lime use and functionality in sulphide mineral flotation

2019-11-1  Lime consumption can, however, be very high, especially for ores with high pyrite content, and/or when flotation is carried out in seawater. For some South American copper ores, pH values as high as 11.5 are needed to depress pyrite, and lime consumption up to 5 kg/t of ore is reported.

Interpretation of high base consumption in the flotation

2004-4-1  The present investigation shows that Ca 2+ ions generated by gypsum makes it necessary to use significantly larger quantities of base (lime or soda ash) to raise pH of the gypsum slurry which is aerated in flotation cell. One possible route to reduce the consumption of base is to use sodium polyphosphate as complexant to bind the Ca 2+ ions
