1. Background. The application of flotation on a reasonable scale within the gold-mining industry commenced in the early 1930s following the introduction of water-soluble flotation collectors (specifically xanthates and dithiophosphate collectors) that allowed differential flotation of sulfide minerals (Weinig and Carpenter, 1937, Rabone, …

Research investigations have until recently typically focused on the individual flotation behaviour of each gold-bearing mineral in synthetic mixtures and not on mixtures of sulfide minerals in 'real' ores ( Teague et al., 1999a ). In the flotation process, the main chemical effects are reagent type and pulp pH.

The addition of lime in the flotation operation is usually carried out by adding the lime powder to the ore belt of the ball mill or adding lime milk or lime powder to the stirring tank before the flotation. The role of lime in the flotation process is most apparently the effect on the properties of the flotation .
Formation of calcium sulphate (gypsum) by the interaction of calcium ions with sulphate ions in the pulp produces fines slime coatings on the sulphide minerals and hinders the flotation of the desired minerals ( Raghavan and Hsu, 1984, Grano et al., 1995, Zanin et al., 2019 ). Sulphate may also increase capital expenditure because of its …
