Smelting of copper concentrates results in the discharge of millions of tons of SO, to the atmosphere each year. Because of increasing concern with air pollution, the Bureau of Mines has developed a hydrometallurgical procedure to obtain elemental sulfur from chalcopyrite by means of the following reaction: CuFeS2 + 3FeCl3 → CuCl + 4FeCl2 + 2S.

However, once you've etched a board with it, you're left with a solution with a bunch of copper chloride in it. This dissolved copper is an environmental problem, and you can't just pour it down the drain (legally) you're supposed to take it to a hazardous waste facility. (For instance: How to .

The copper concentrate can be directed back to the chloride leaching circuits. Conclusions The elemental sulfur formed during the ferric chloride leaching is discretely crystalline in nature. The size of the sulfur particles is in the range of 5 to 10 microns and is about an order of magnitude smaller than the size of chalcopyrite or pyrite (4070 microns).

The chalcopyrite flotation concentrate can be sent back to chloride leaching circuits. Elemental sulfur produced by chloride leaching of sulfide ores or concentrates contains selenium and tellurium usually too high to be used in various industrial or agricultural uses.
in ferric chloride medium [710]. The overall reaction rate was controlled by chemical kinetics, probably by the generation of an elemental sulphur layer on the leached mineral surface. Carbon tetrachloride, CCl 4, was used as a solvent for the elemental sulphur produced during the chalcopyrite leaching by ferric chloride [11]. These
