Sulphur Refining of Gold Mineral Processing & Metallurgy

Refining with Sulphur A more speedy method of removing iron, copper, lead and base metals from bullion is to add sulphur to the molten metals. Although gold sulphides may be readily formed in the wet way, they are decomposed into gold and sulphur by merely heating them to a temperature below 300 deg. C. If pure gold is heated strongly with sulphur no combination of the elements appears to take

Sulfide Ores an overview | ScienceDirect Topics

If sulfide ores containing iron and copper are to be smelted, an understanding of both the iron and the copper systems is needed. Again, as in Figure 2.1.3 for the Cu–S–O system, the calculations are limited to oxidation by industrial oxygen so that the pressure of SO 2 will be about 1 atm., except where oxygen pressure is appreciable near
