Hydrometallurgical Copper Extraction Process

Dec 15, 2018 Very simply, it converts copper concentrates of varying composition into copper metal which has been proven to be equivalent in every way to electrolytic tough pitch copper suitable for electrical applications.

metallurgy and hydrometallurgy copper Industrial

The copper is deposited on the cathode and the gases produced at the anode (O 2, Cℓ 2) are recovered selectively and returned to the process. This method produces an extremely pure copper that can then be rolled (hot or cold), drawn or even formed into tubes before being sold. Wastewater treatment is extremely important in these factories.

Hydrometallurgical Process an overview ScienceDirect

The hydrometallurgical process included pressure leaching under slightly oxidising conditions in diluted sulphuric acid (at 80–105 °C and 140-350 kPa oxygen pressure). This enabled selective extraction of up to 97% of copper, with less than 10% of pyrite taking part in the reaction.

This process consumes 2,500 to 3,000 kWh · t –1 of copper produced. The copper is deposited on the cathode and the gases produced at the anode (O 2, Cℓ 2) are recovered selectively and returned to the process. This method produces an extremely pure copper

US5223024A Hydrometallurgical copper extraction process

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

Copper Mining and Processing: Resources and Glossary

For copper oxide ore, electrowinning is the final stage in the process of hydrometallurgy, in which concentrated copper solution from the heap leaching and solvent extraction processes is used as an electrolyte; an electric current is applied through an inert anode, resulting in the plating of copper onto 99.9% pure copper cathodes.

Cementation (metallurgy) Wikipedia

Cementation is a type of precipitation, a heterogeneous process in which ions are reduced to zero valence at a solid metallic interface. The process is often used to refine leach solutions.. Cementation of copper is a common example. Copper ions in solution, often from an ore leaching process, are precipitated out of solution in the presence of solid iron.
