copper extraction from ore

US5316567A Hydrometallurgical copper extraction process Google

A process for the extraction of copper from a sulphide copper ore or concentrate comprises the steps of subjecting the ore or concentrate to agitation leaching at an elevated temperature and pressure to obtain a resulting acidic leach liquor containing dissolved copper and reducing the acidity of the resulting acidic leach.

Picture 4 shows the distribution of these deposits. About 80% of all copper extracted comes from sulphide ores. A typical ore contains only 0.5% to 2.0% copper. It is a measure of the value of copper that it is worth extracting it from such small concentrations. The ore is a mixture of minerals and rock (called gangue).
