Abstract
Run-of-mine coal and pre-washed coal from Santa Catarina, Brazil, were characterized using washability curves, and by particle analysis after crushing. Bench-scale froth flotation tests were then conducted with the pre-washed coal, using kerosene and diesel oil as the collectors and pine oil as the frother. The influence of starch (as depressor) on flotation was also studied. The effects of feed particle size; pH; collector, frother and depressor additions; and flotation time were investigated. A 9.5% ash content coal was obtained with a mass recovery of about 29%. (17 refs.)
