Abstract Beneficiation of lowgrade ore is of critical importance in order to meet the growing demand for coal and mineral industries. But, lowgrade ores require fine grinding to obtain the desired liberation of valuable minerals. As a result, production of fine particles makes the beneficiation process difficult through conventional gravity separators. Hence, alternative beneficiation ...
