Flotation test of entire −0.5 ... Typical results in a coal beneficiation plant using spirals to treat fine coal indicated very little deterioration in performance with the under-slimed and deslimed feed material (−500 mesh) even when the feed contained ~50% of −500 mesh material. However, the clean coal ash reduced when the −500 mesh ...
The flotation agent is used to selectively attach useful minerals or useless impurities to the bubbles for the purpose of separation. This method is also called chemical beneficiation. A standard flotation …
