Ore washing for bauxite. Generally, the gibbsite type and diaspore type bauxite with more mud and lower grade are washed to obtain the raw material for alumina production. At present, for easy-washing bauxite ore, the two-stage ore washing process using cylinder washing machine (also referred to as drum washer) and trough washing machine is ...
Ore washing is the process of using water or mechanical force to agitate and scrub raw ore, thereby separating clay and other impurities from the ore. Alluvial ore deposits, such as gold, platinum, tungsten, and tin, along with other minerals like lead, copper, iron, and manganese, undergo deep oxidation and weathering.
