Jan 23, 2012 Step 8 – Refining (off site) Once basic processing is done, the ore is taken to a refinery where the remaining impurities are stripped out. Crude gold is melted and treated with chloride, which converts any remaining foreign metals to chloride which will then drift off the gold. The result is 99.5 pure gold, which is then cast into.Get Price
We have a unique chemistry that allows us to aggressively process precious metals at 20 mesh and below in less than one hour, so we can effectively leach black sands without dissolving the majority of their iron content.

When smelting assays are done on high sulfide ores, a couple of iron nails are added to the mix. The metal in the nails reacts with the metals in the sulfides reducing the metals to their metallic state. This is handy when processing silver containing minerals to convert them to silver metal.
Slag A vitreous mass that separates from fused metals during smelting or refining of metalliferous material. Smelting Treatment of metalliferous material, typically a metal sulfide ore or concentrate, with sufficient heat to cause melting of the sulfide mineral(s) in the ore or concentrate such that a molten metal sulfide phase is formed.

In Pergamon Materials Series, 1998. 10.6.6.1 Matte slag gas reactions in Cu Fe Ni sulphide ores. Sulphide ores are a major source of Cu, Ni and precious metals. A basic principle of the extraction processes is to blow air into the molten sulphide in order to oxidise (1) S, which forms a gas and (2) Fe, which forms predominantly FeO and then partitions to a slag phase which covers the matte.
The contribution of the milling, smelting, and refining of sulfide ores to Hg emissions and to Hg byproduction is not adequately quantified in a global context. In this study, we estimate Hg emissions from the pyrometallurgical treatment of Cu, Pb, and Zn sulfide ores. We base our calculations on qu.
In hydrometallurgical processes, nickel sulfide ores undergo flotation (differential flotation if Ni Fe ratio is too low) and then smelted. After producing the nickel matte, further processing is done via the Sherritt Gordon process. First, copper is removed by adding hydrogen sulfide, leaving a concentrate of only cobalt and nickel.
