The waste treatment processes for copper plating solutions and copper-containing rinse waters are well known and in .Innovations: Introduction to Copper: Mining & ExtractionThe barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.Copper Mining and Extraction: Oxide OresThe process used to treat sulfide copper ores begins at the mine site, where the copper-bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining.

Processing, smelting and refining gold | World Gold Council

***copper remains in gold The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process. The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold.Reference Guide to Treatment Technologies for Mining ...natural vegetation.2 Passive treatment systems use gravity flow for water movement, and passive energy sources such as solar or wind power. In some arid climates, they might also include the use of evaporation or infiltration.
