Mining and Refining – Process - World Aluminium

Ore quality can be improved by relatively simple and inexpensive processes for removing clay, known as “beneficiation”, which include washing, wet screening and mechanical or manual sorting. Beneficiating ore also reduces the amount of material that needs to be transported and processed at the refinery. However, the benefits of beneficiating need to be weighed against the amount of energy and water used in the process …

Mining organisms inhabiting iron ore deposits are implicated in biomineralization processes …

Beneficiation of bauxite

A primary objective of the beneficiation process is to reduce the silica content in the ore, as the latter reacts with caustic soda during the digestion step to precipitate out as insoluble sodium aluminium silicates, e.g. 2Na2O.2Al20;,.3Si02.2 H20. This salt is eliminated from the process along with the insoluble iron and
