The Gabriela Mistral, or Gaby, mine was a greenfield oxide copper project in remote northern Chile. Each day, the solvent extraction and electrowinning (SX / EW) plant would produce some 430 metric tonnes of quality copper from the open pit mine. Stateofthe art technology was used in all of the processing facilities, which included those for

The runofthemine (ROM) ore from the primary crusher at the Santa Rita openpit undergoes secondary crushing and grinding followed by conventional frothflotation at the Ivanhoe concentrator for the production of copper and molybdenum concentrates. The SX/EW produces copper cathode by processing the solution generated by ROM leaching.

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 highgrade 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

The leaching, solvent extraction and electrowinning (LXSXEW) process is a widely used method in the production of copper from lowgrade oxidized ore. Copper is the most common metal to be processed by LXSXEW, but the process can also be used to extract, purify and concentrate other metals, such as nickel, cobalt and zinc.

How Hydrometallurgy and the SX/EW Process Made</h3>IntroductionConventional Copper ExtractionThe SX/EW ProcessBacterial LeachingConclusionContacts and ReferencesAlso in This IssueThe SX/EW Process is a hydrometallurgical process since it operates at ambient temperatures and the copper is in either an aqueous environment or an organic environment during its processing until it is reduced to the metal. Because of its dependence on sulfuric acid, the SX/EW Process is at present not a substitute for, but rather an adjunct to conventional smelting.
