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.
From ore to dor. 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 ...
Zinc (Zn) was used in Rome and China more than 2000 years ago as a component of brass which is a zinc-copper alloy. The Romans and Chinese smelted zinc ores such as calamine (zinc carbonate) with copper to produce brass, used for coins, containers, armour and jewellery. They did not actually realise that zinc was a metal.
