gold ore desulfurization

Environmental desulfurization of mine wastes using

The environmental desulfurization of tailings is one approach that has gained much popularity in the last two decades. It was defined as an alternative, integrated tailings management technique that can be accomplished through froth flotation (Benzaazoua et al., 2000, Demers et al., 2009).This method aims to remove sulfide and sulfosalt minerals (flotation concentrate) from gangue minerals (e ...
