This paper introduces a new potential method of pyrite depression in the flotation of high sulfur coal based on the electrochemical pyrite surface control. Experimental date show that the natural hydrophobicity of pyrite depends on the oxidation-reduction potential of the pulp. The mechanism and products of electrochemical reaction on the pyrite surface are also discussed under various conditions. The pyrite flotation is generally suppressed under low pulp potentials. Therefore, the sulfur removal in the flotation of high sulfur coal could be improved by the pulp redox potential control, while the coal flotation is materially not affected.
