Silver chloride may then be processed with zinc, sodium hydroxide, and dextrose reduction. Fusion melting is a process that alloys silver and platinum group metals with lead. This process uses zinc which is later removed from the slag. The remaining high-grade silver will still need further refining to meet a target purity of 99.9% …

In this method, the ore is heated until it becomes molten. As the mixture of metals is allowed to cool, a crust of zinc and silver forms on the surface. The crust is removed, and the metals undergo a distillation process to remove the zinc from the silver. To extract silver from copper-containing ores, an electrolytic refining process is used.
Details
The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ( CuFeS2 C u F e S 2) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper.
