Flotation is the most effective separation solution used in sulphide ore beneficiation. In sulphide ore flotation, the interaction between the valuable sulphide minerals and the gangues are complex.

Mineral Flotation International Mining

“Flotation reagent selection is paramount and test work is necessary to ensure the optimum reagent suite is utilised. If the ore contains a low amount of iron sulphides, xanthate collectors are often suitable to float copper sulphideminerals. If native gold is present, dithiophosphates can be used which are less selective to iron sulphides.

The utilization of citric acid as a depressant for the ...

Microflotation and real ore flotation were used to describe the flotation behaviour and separation performance of these two minerals. Zeta potential measurements, adsorption experiments, ICPAES tests, SEMEDS analysis and solution chemistry calculations were conducted to understand the interaction mechanism between CA and mineral surfaces. 2.

Formula (5) is used in making tabulations for mill use. As used in these formulas the specific gravity of the ore is obtained simply by weighing a liter of mill pulp, then drying and weighing the ore. With these two weights formula (2) may be used to obtain K, and then formula (1) to convert to S, the specific gravity.
