Copper extraction - Primary orebody formation

Currently, the most common source of copper ore is the mineral chalcopyrite (CuFeS2), which accounts for about 50% of copper production. The focus of this article is on the process of copper extraction from chalcopyrite ore into pure metal. Processes for other minerals are mentioned. For economic and environmental reasons, many of the byproducts of extraction are reclaimed. Sulfur dioxide gas, for example, is captured and turned into sulfuric acid - which is then used in the extraction process. Copper e ...

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. The next major step in production uses pyrometallurgical processes to convert the copper concentrate to 99% pure copper suitable for electrochemical refining. These high temperature processes first roast the ...

Copper extraction - Oxide ores. Oxide ores are readily leached by sulfuric acid, usually using a heap leach or dump leach process in combination with solvent extraction and electrowinning technology (SX-EW). Commonly sulfuric acid is used as a leach for copper oxide, although it is possible to use water. There have been examples where froth flotation was used to concentrate malachite. In general froth flotation is not used to concentrate copper oxide ores, as the cost of leaching is cheap when compared to the cost of grinding and flotation. The implication of this is th ...

To a large extent, copper oxide and sulfides are naturally separated in nature. As such, once mined the processing of the ore generally does not need to separate the oxides and sulfides. Copper extraction - Primary orebody formation. Copper orebodies are formed when geothermal solutions bring copper dissolved from deep underground to cool near surface environments where the copper and associated metals precipitate as minerals in veins and disseminations within the rock. Copper is usually deposited as copper sulfide minerals or ...
