Beneficiation of the gold bearing ore by gravity and .Traduire cette page

25/01/2012 · Gold concentration usually consists of gravity separation, flotation, cyanidation, or the combination of these processes. The choice among these processes depends on the mineralogical characterization and gold content of the ore. Recently, the recovery of gold using gravity methods has gained attention because of low cost and environmentally friendly operations.

Gravity/Flotation test protocols | GekkoTraduire cette page

Gekko's IPJ and flash flotation are processing methods which remove gold or other minerals from a comminution circuit. They are complementary technologies and in many cases have been used together to maximise gold recovery in size ranges at which they operate. The combination of flash flotation and continuous gravity recovery covers the full size range from 10μm up to millimetres sizes ...
