Flash Flotation Of Coal

Pyrite is removed from coal by means of a two stage froth flotation process In the first stage coarse pyrite is removed as underflow in a conventional froth flotation operation In the second stage the froth product from the first stage is subjected to froth flotation using a coal flotation depressant and a pyrite flotation collector thereby removing a substantial proportion of fine pyrite.Jun 07 2017 Flotation separation Flotation is the most widely used method for the concentration of fine grained minerals It takes advantage of the different physicochemical surface properties of minerals—in particular their wettability which can be a natural property or one artificially changed by chemical reagents.
