Enhanced flotation selectivity of fine coal from kaolinite

The flotation tests were conducted in a 0.5 L micro-flotation cell under 1906 rpm impeller speed. The solid concentration was about 60 g/L. The anionic polyacrylamide dosage was 0 g/t, 33 g/t, 66 g/t and 100 g/t flotation feed. The collector and frother were kerosene and sec-octyl alcohol. Their dosage was fixed at 4000 g/t and 500 g/t

Commerce Resources Corp. Announces Flotation Pilot

13.04.2021 · The work resulted in a marked improvement in flotation performance as demonstrated through a combination of distributed reagent additions, reagent synergism, and reverse conditioning in a very simple and basic flotation circuit. The performance included a considerable reduction in reagent consumption to one-half to one-quarter of the quantity (kg/t) of that utilized in prior test work by other
