Applying High Salinity Water in Flotation-A Review

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 [8].
