Sulphide Flotation - an overview | ScienceDirect Topics

Many copper–gold concentrators have a combination of flash flotation and gravity separation in the milling circuit to enhance overall free gold recovery. The reason for the inclusion of gravity separation at these concentrators is that the coarse free gold is not recovered effectively in the flash flotation cell. Concentrators that have this circuit configuration have found that most of the ...

The flotation process in general does not float free gold particles but is particularly effective when gold is associated with sulfide minerals such as pyrites.

Free Gold | Gekko

If the ore product contains a combination of coarse and fine free gold, the modular Gravity Flotation Intensive Leach (GFIL) system can produce a higher-yield 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.
