ESCA Analysis of Flotation Reagent BET Reaction on Coal

Through the analysis with ESCA charts, it has proved that BET on the surface of Coal is absorbed by adding the BET as the increasing. The BET is not adsorbed basically on the surface of pyrite. The major difference between coal-pyrite and mineral-pyrite lies in

The selectivity of the flotation process was highest for this fraction (ash reduction 17%), however, the corresponding recovery of coal was very low (35%). The enhanced separation of coal and mineral matter in this case, is most probably attributed to the presence of high ash fines in the feed, which was confirmed by microscopic examination....

Upgrading difficult-to-float coal using microemulsion

The procedure is called direct contact flotation. It relies on mixing dry coal either with pure (anhydrous) flotation reagent(s) or microemulsion. By applying the new direct contact flotation procedure, a coal yield reaching > 95% using anhydrous flotation reagents was achieved, but with relatively high consumption of reagents (up to 30 g/kg).
