copper iron flotation in south africa

The practice of pyrite flotation in South Africa and ...

1991-1-1  The flotation of pyrite is of great importance to the gold mining industry in South Africa and Australia. The flotation plants fall into a number of categories, viz. flotation after milling, flotation of current residues and reclaimed residues, flotation of refractory ores and the flotation of gold-copper ores.

2020-11-24  In both countries, copper sulphate is often used as an activator, although the dosages are quite different (South Africa ≈40 g/t, Russia ≈10 g/t). However, recently, there has been a reduction in the use of copper sulphate on flotation plants. In South Africa, sodium ethyl dithiophosphate is often used at a dosage of ≈60 g/t.

Comparing lead and copper activation on pyrite with ...

2021-7-1  For example, in a number of gold flotation plants in Australia and South Africa, copper ions are added to flotation cells to improve pyrite flotation (O'Connor and Dunne, 1991, Hodgkinson et al., 1994). Copper activation on pyrite has been considered as an electrochemical process where adsorbed Cu(II) on pyrite surface is reduced to Cu(I).

Effect of Flotation Parameters on Recovery of South Africa ...

This study investigated the effects of flotation parameters on the recovery of low grade nickel sulphide ore. The parameters investigated are the particle size, flotation time, temperature and pH of the pulp. The analyses of the results obtained showed that particle size, pH, and flotation time had significant effects on the recovery of nickel sulphide ore.
