FLOTATION Native gold and gold in sulphide minerals is readily floatable. Therefore, it is often possible to achieve high gold recovery (>90%) in a flotation concentrate. This results in a reduction of up to fifty times in the mass of goldbearing material for further processing. This is particularly advantageous in the

A simpler flotation circuit with lower operating and capital costs for treatment of such coppergoldpyrite ores with an elevated pyrite head assay was sought in this work. After characterizing the ore, the objective was to apply bulk rougher flotation of both the copper minerals and pyrite for the coppergoldpyrite ore at natural pH.
The flotation of gold and silver minerals is mostly carried out in alkaline pulp medium, but for some goldbearing pyrite and pyrrhotite, it is suitable for flotation in weak acid pulp medium. Oxygen has an effect on the flotation process of goldsilver sulfide ore oxidized to different degrees.

If the ore product contains a combination of coarse and fine free gold, the modular Gravity Flotation Intensive Leach (GFIL) system can produce a higheryield product. For ores smaller than 50 micron, the particle weight is too light for physical separation by gravity; therefore gold recovery will require a modular chemical flotation process.
