The Effect of Chemical and Bacterial Suppresion of Pyrite During Coal Flotation

Abstract

This work studies the ffect of biooxidation and chemical suppression on the floatability of pyrite in selected coals. Initial experimental work involved the optimization of a standard coal flotation systems using a Leeds laboratory flotation cell. The results of this study provided the baseline data for subsequent comparative tests. The influence of various chemical depressants on pyrite recovery during flotation was determined and compared with bacterial methods for pyritic suşphur depression
