Gold flotation is widely used in the case of refractory ores, in which small-sized gold particles, locked within sulfide minerals, are recovered through flotation of gold-bearing minerals (Marsden and House, 2006). It is also an effective means for separating free gold from silicate particles present in ore.

EXPERIMENTAL Laboratory and Bench-Scale Separation Tests To compare the performance of conventional flotation and HydroFloatTM separators, a series of tests were conducted using a coarse sample of ore obtained from an operating gold concentrator.
Froth Flotation Process
The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to carefully separate them from one another and the slurry they are in. For this purpose we use chemicals/reagents: Frothers (MIBC) is …

Fine Gold Recovery by Flotation
Gold Flotation Column. The flotation column was developed for the improved recovery of fine particles too, and is finding commercial application. It embodies principles which are, with modification, appropriate for the flotation of gold from coarse dense sands. A small laboratory column, 1 m high by 50 mm in diameter (Figure 2), was …
Flotation of gold and gold-bearing ores
A great deal of work has been reported on specific ores, but such studies rarely distinguish between the flotation of native gold and other gold minerals. Flotation of gold ores covers a broad field and it is a rather difficult subject to generalize on. Most problems in gold ore flotation are not connected with floating metallic gold.
