Beneficiation of Coal Fines by Aggregative Flotation ...

01/10/1984  The effect of various operating parameters on the performance of the aggregative flotation process for beneficiating coal fines was investigated. The recovery of carbonaceous matter was found to be improved by high mixing intensity and by the utilization of preemulsified collector in the aggregate formation stage. The presence of salt in the flotation stage was found to enhance recovery of the ...
