To our geologists at Eldorado Gold Corporation, the release of the gold assays on a new ore zone causes a flurry of excitement. But to our metallurgists, that news is often greeted with the question What's the sulfur grade'? In our company, we operate and manage projects whose end-product will either be auriferous sulfide flotation concentrate or gold dor.

Gold Ore Roasting Plant. It is characteristic of the roasting of gold-containing ores that the highest recoveries are obtained within a rather narrow range of roasting temperatures and oxygen partial pressure in the roaster gas Ores of sufficient sulfur and carbon content can be treated autothermally Some ores with low sulfur and carbon contents call for additional.

2016-3-23 · Sulphur Refining of Gold. 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.

2008-12-1 · Because gold is believed to be mostly transported as bisulfide complexes in orogenic deposits (e.g., Groves et al., 2003; Goldfarb et al., 2005), the source of the sulfur is important to the understanding of the source of Au, the source of the hydrothermal fluids, and the genesis of the deposits.However, the S source of such deposits has been equivocal for many decades.

2020-10-5 · Another aspect remain controversy is the source of gold, with some researchers claim that gold was sourced from pre-ore stage pyrite (Shen, 1996; Zhang and Shen, 1996) while others claim that Au (and sulfur) came from ore-forming fluid (Chen et al., 2015). The key to solve this problem may lie in determination of the Au concentration of the pre ...
