Flotation is the most common beneficiation method used for ores that contain metal and industrial minerals. Flotation was developed for the beneficiation of minerals, but it can also be used for the treatment of recycled materials, remediation of contaminated soil, de-inking of paper, and water treatment, for example.
Flotation of coal using sea water The reason that sea water has been applied for coal flotation is mainly because in 1920 some coals were reported to be readily floated in sea water without the addition of reagents (collector and frother). In 1930’s, the flotation of coal using sea water was further investigated by Russian researchers .
