Innovations in Copper: Mining & Extraction: Producing ...

Prior to the development of the solvent extraction-electrowinning (SX/EW) 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.

Ruashi Mine - Wikipedia

The Ruashi Mine is an open-pit copper and cobalt mine operated by Metorex that is located about 10 kilometres (6.2 mi) from Lubumbashi in Katanga Province, Democratic Republic of the Congo.

Copper recovery using leach/solvent extraction ...

Copper recovery by L/SX/EX in 1968 In 1968 there were only two widely practiced copper leaching processes using dilute sulphuric acid. The first process, vat leaching of high-grade copper oxide ore followed by EW of copper from the leach solution, produced low quality copper cathode at relatively high cost. In 1968 the tonnage of high-
