Gold Extraction & Recovery Processes

Extensive use of sisal clothes as sluice boxes liners to concentrate gold was employed in mining operations in Africa. The main problem is to use very opened sisal clothes than can work properly for coarse gold, but it is unlikely efficient for medium and fine gold particles. This material costs around US$ 4/m2.

How Gravity Separation Works to Recover Metals and Minerals

This rudimentary piece of mineral processing equipment uses pulses of water to suspend the particles in water. As the pulses dissipate, the particles settle in the bottom of the jig. Particles with a higher specific gravity (like gold) settle faster than those with a lower specific gravity, effectively separating the gold so it can be collected.
