Hydrometallurgy - an overview | ScienceDirect Topics

In 1947, Colmer et al. isolated At. ferrooxidans from acid mine drainage and found that the strain could oxidize Fe 2 + into Fe 3 + to leach copper from pyrite, which was the first reported bioleaching (Colmer and Hinkle, 1947).Subsequently, bioleaching of minerals developed rapidly (mainly sulfide minerals, including acid-soluble sulfide minerals and acid-insoluble sulfide minerals) (Bryner ...

Ore Beneficiation - an overview | ScienceDirect Topics

In most ores, including iron ore, valuable minerals are usually intergrown with gangue minerals, so the minerals need to be separated in order to be liberated. This screening is an essential step prior to their separation into ore product and waste rock. Secondary crushing and screening can result in further classification and grading of iron ore.

Crusher - Wikipedia

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
