It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy. The primary operations are comminution. Keeping this in view, what is recovery in mineral processing? The recovery is the amount of a valuable substance that has been recovered into the concentrate from its initial amount in the

Alluvial gold is found beneath the surface at the bottom of a creak or stream. Alluvial gold mining is the process of extracting gold from these creaks, rivers and streams and is generally considered to be the most environmentally friendly method of gold mining as a result of the reduced environmental impact when compared to underground mining.

Tailings can be stored below ground in previous worked out voids. The tailings are generally mixed with a binder, usually cement, and then pumped underground to fill voids and help support an underground mine. For example a 'room and pillar' mining operation that uses backfill will be able to extract the insitu pillars containing ore.
