However, with pressure to reduce water usage, old dry beneficiation technologies have been reconsidered while new techniques are starting to be developed. In the last few years, dry concentration has played an important role in coal beneficiation, due to the increase in its separation efficiency, as well as the non-use of water [ 13, 14 ].
