202241 · The most widely used beneficiation techniques are flotation, direct carbonation, electrostatic up-gradation, calcination, and leaching/bioleaching. Bioleaching has environmental benefits and electrostatic up-gradation can achieve the highest quartz removal efficiency, although this is an energy-intensive process.

At last, bio-beneficiation technologies are achieved by specific bacteria. Sometimes the combination of two or three beneficiation technologies is needed to achieve an effective beneficiation process of low rank coals.
view moreFlotation This is a partly physical and partly chemical beneficiation used to concentrate ores of copper, lead, and zinc. These metals have considerable affinity for sulfur. (the table on the metallurgy section lists sulfide ores for each of them.) The ore is ground and suspended with water in large tanks. Flotation agents such as the xanthates are added and a stream of …
