The 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. The smelting stage gives the name pyroprocessing

system to leach gold over copper from oxidised ores has been tested successfully using different gold–copper ores (Drok and Ritchie, 1997; La Brooy et al., 1991; Muir et al., 1989). However, this system in the treatment of transition or sulphidic ores gave poor gold recovery and required higher reagent concentrations (Muir, 2011). Moreover, both

From ore to doré. More gold is recovered by cyanidation than by any other process. In cyanidation, metallic gold is oxidised and dissolved in an alkaline cyanide solution. When gold dissolution is complete, the gold-bearing solution is separated from the solids. With ores of higher gold content (greater than 20 grams of gold per tonne of ore

The process of liberation of copper ores depends upon whether they are oxide or sulfide ores. Subsequent steps depend on the nature of the ore containing the copper and what will be extracted. For oxide ores, a hydrometallurgical liberation process is normally undertaken, which uses the soluble nature of the ore minerals to the advantage of the

In addition to processing copper ores, new and old copper scrap or copper alloys can be melted, re-purified, and recycled into new components. It is estimated that such recycling supplies 50% of copper used in the copper industry (Scott, 2011). In 2010, 770,000 metric tons of copper were recycled, at an estimated value of nearly six billion dollars (Papp, 2010).

Gold is heavy and highly malleable. Gold will not change color, crumble, or tarnish, and is unaffected by most solvents. Gold is commonly alloyed with silver and other metals. The ore may, therefore, contain sulfides like arsenic, copper, iron, and silver. Gold ore does not usually have any shiny gold on the surface. Spotting it with the
