Extraction Copper information provided by Copper

Extraction Copper information provided by Copper

Leaching offers an alternative to copper mining. First, the ore is treated with dilute sulphuric acid. This trickles slowly down through the ore, over a period of months, dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by electrolysis. This process is known as SX-EW solvent extractionelectrowinning.

TENORM Copper Mining and Production Wastes

TENORM Copper Mining and Production Wastes

Solvent extraction. Once PLS is leached, it is sent to a solvent extraction plant to remove the copper. The PLS is mixed with an organic solvent that binds to the copper and chemically separates the copper from the rest of the liquid. Then, the copper-bearing liquid is combined with another acid to precipitate the copper from the organic material.

Copper Mining and Extraction Oxide Ores

Copper Mining and Extraction Oxide Ores

The solvent extraction phase of treatment occurs in two stages. During the initial phase an organic solvent is used to recover copper ions contained in the pregnant leach solution, exchanging them with hydrogen ions in the acid. The final phase of the solvent extraction process employs a strong acid to strip the copper from the organic solution ...

Innovations in Copper Mining amp Extraction Producing

Prior to the development of the solvent extraction-electrowinning SXEW process in 1959 see Copper the Green Metal, the only way to recover copper from an acid solution was by a process called cementation. In this process, copper was in effect traded for iron by contacting the copper-bearing solution with scrap iron.
