Application of biotechnology in iron ore beneficiation

Poorni and Natarajan (2013) investigated the role of B. subtilis, and the adaptation of B. subtilis, in the beneficiation of a de-slimed bauxite ore. In flocculation trials, corundum-adapted B. subtilis cells were able to facilitate the removal of approximately 96% of iron after 5 min interaction at pH 7 to 9.

22.4: Beneficiation

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 latter can be suspended in a stream of water and flushed away. The iron ore magnetite, Fe 3 O 4, is ferrimagnetic. It can be separated from abundant deposits of taconite by grinding to a ...

Literature quest and survey on graphite beneficiation

However, the beneficiation of graphite ore is pivotal as it accounts for the quality, market price and suitability for various technological applications including energy storage in lithium-ion batteries. Since graphite is spontaneously hydrophobic (like coal) in nature, flotation is the common and apt technique for beneficiation of graphite ore.
