Coal flotation - bench-scale study. Flotacao de carvao estudo em escala de bancada

Abstract

Run-of-mine coal and pre-washed coal from Santa Catarina, Brazil, were characterized using washability curves and by particle size analysis after crushing. Bench-scale froth flotation tests were then conducted with the pre-washed coal. Kerosene and diesel oil were used 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 addition, frother addition, depressor addition and flotation time were investigated. A 9.5% ash content coal could be obtained with a mass recovery of about 29%. (17 refs.)
