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 ...

Developing Copper Arsenic Resources with CESL .

The success of the CESL Process in processing arsenic-bearing copper concentrates, at levels of up to 4.6% arsenic, has been previously presented. The present paper discusses aspects of similar, equally successful trials on copper concentrates with grades of arsenic approaching 12%. Key parameters to the successful processing of these types of concentrates are discussed. In addition, data on ...

Copper - Wikipedia

The process of recycling copper is roughly the same as is used to extract copper but requires fewer steps. High-purity scrap copper is melted in a furnace and then reduced and cast into billets and ingots; lower-purity scrap is refined by electroplating in a bath of sulfuric acid. Alloys. Copper alloys are widely used in the production of coinage; seen here are two examples - post-1964 ...
