gold ore desulfurization

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 ...

The Merrill Crowe Process - evoqua

Today, one of the most popular methods for gold extraction is the Merrill Crowe process. The process can be summarized as follows: The zinc, cyanide and gold ore are mixed. The gold has an affinity to the zinc and cyanide particles and forms deposits on the surface of the zinc. The zinc and gold particles are then filtered out using a filter ...
