Hydrometallurgical techniques are quickly gaining acceptance as a reliable and cheap method for extracting copper from their ores. Compared to conventional extraction methods such as froth flotation, smelting and refining, hydrometallurgical techniques are slower and generally reserved for low grade ores or mine wastes.

A process for the extraction of copper from a copper ore or concentrate comprises first subjecting the ore or concentrate to agitation leaching at an elevated temperature and pressure in the presence of oxygen and water to obtain a resulting acidic leach liquor which contains dissolved copper. The acidity of the resulting acidic leach liquor is then reduced by affecting percolation leaching of

The following is a process of copper extraction from chalcopyrite ore into pure metal. While oxide ores can be processed using pyrometallurgical techniques, hydrometallurgical methods are more cost effective. The copper ore is crushed and ground before it is concentrated to between 20 and 40% copper in a flotation process.

Hydrometallurgy is a technique within the field of extractive metallurgy, the obtaining of metals from their involve the use of aqueous solutions for the recovery of metals from ores, concentrates, and recycled or residual materials. Processing techniques that complement hydrometallurgy are pyrometallurgy, vapour metallurgy, and molten salt electrometallurgy.
