dirty water in a coal flotation circuit

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 1930s, the flotation of coal using sea water was further investigated by Russian researchers 8.

US3856668A Method for treatment of coal washery waters

Coal washery waste waters are clarified in a two-step process in which coal particles are first agglomerated and removed from the water. Thereafter, the inorganic mineral constituents contained in the waste water are separated to leave a clarified water stream suitable for reuse. Agglomeration of the coal particles is accomplished by intense mixing of a heavy hydrocarbon, preferably in the ...
