They argue that the hydroxide precipitate from the dissolved mineral species adsorbs on the coal surface and makes surface hydrophilic. It was concluded that the presence of these species can be controlled by manipulating the pH at different stages of processing depending on coal type. 4. Aggregation in the coal flotation pulp

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 ...
