Micronized coal beneficiation by froth flotation process
The Froth flotation technique has not been widely applied industrially to separate processing of the ultrafine size fraction of coal. This is due to the low efficiencies and costly operations that make the treatment of ultrafine coal by froth-flotation uneconomical. A study of the effect of dosage of various reagents such as MIBC, Fuel Oil/MIBC, and Fuel Oil/Shur-coal (2027), on micronized coals have been performed to establish the optimum level of reagents at which the froth-flotation technique is economically viable. The recovery of ultrafine size fraction of coal by the froth flotation process has been correlated to the particle size, type of reagent, and the dosage of the reagent(s) used.
