gold ore gravity concentration process increase quality

Mineral processing

Gravity separation dates back to at least 3000 BC when Egyptians used the technique for separation of gold. It is necessary to determine the suitability of a gravity concentration process before it is employed for concentration of an ore.

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.

The gravity concentration separation process gets more complex as the specific gravities between the valuable mineral and the gangue get closer. For example, complex gold in a sulphide complex of pyrite, must isolate a specific gravity of 19.3 for gold from 5.2 for pyrite. Using gravity to recover minerals in their coarsest fraction minimises

Concentration means increasing the amount of gold in ore or sediment, by selectively removing lighter particles. If employed effectively, concentration methods can eliminate or greatly reduce the need for mercury. Before concentration can begin, ore must be crushed or milled to liberate gold particles from rock and to decrease grain size.
