As different from bioleaching, the use of microorganisms in mineral beneficiation is illustrated with examples from iron ore, bauxite, clay, and sulfide mineral beneficiation for selective removal of undesirable impurities.
Beneficiation, removal of worthless particles from pulverized metal ore. See mineral
Beneficiation is any process that improves (benefits) the economic value of the ore by removing the gangue minerals, which results in a higher grade product (ore concentrate) and a waste stream (tailings). There are many different types of beneficiation, with each step furthering the concentration of the original ore.
Beneficiation is any process which removes the gangue minerals from ore to produce a higher grade product, and a waste stream. Beneficiation may involve physical or chemical processes. Often, as in the case of panning for gold, the desired ore or metal is denser than the gangue.
The objective of beneficiation is to remove the noncoal mineral matter from the coal to provide a consistent quality with improved calorific value and reduced ash content in the cleaned coal. Coal beneficiation4 can be divided into two groups: physical and chemical beneficiations.
Beneficiation includes crushing, grinding, gravity concentration and flotation concentration. Beneficiation is followed by processing activities such as smelting and refining. The beneficiation process begins with milling, which is followed by flotation for further beneficiation.
The meaning of BENEFICIATION is the treatment of raw material (such as iron ore) to improve physical or chemical properties especially in preparation for smelting.
