An SX-EW operation is an acid plant. It takes copper out of solution and replaces it with protons which make their way, via the organic extractant, back to the raffinate stream. In heap leach operations the acid is consumed during leaching. In a concentrate leach scenario, it may be more difficult to integrate the
The run-of-the-mine (ROM) ore from the primary crusher at the Santa Rita open-pit undergoes secondary crushing and grinding followed by conventional froth-flotation 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.
Carbonate concentrates are a relatively minor product produced from copper cementation plants, typically as the end-stage of a heap-leach operation. Such carbonate concentrates can be treated by a solvent extraction and electrowinning (SX-EW) plant or smelted.
extraction and electro-winning (SX-EW) plants where the oxide orebodies are being depleted, and the mines will start moving into transitional and sulphide zones. With the FL ROL process, a grinding circuit with bulk flotation can be added upstream of the existing SX-EW plant, and a bulk concentrate can be leached.

Process description In the flowsheet developed by Avmin for the Nkomati base metal refinery, copper, nickel, and cobalt from a sulphide flotation concentrate are dissolved using fine grinding, followed by pressure leaching. Copper is recovered from the leach liquor by solvent extraction (SX). A bleed stream of the copper
Located 10 km from Ndola, the Bwana Mkubwa SX–EW plant (BMML) was established by First Quantum Minerals (FQM) in 1998 to process oxide tailings from dams in the area. In 2003, the plant was redesigned and expanded to process oxide ore from the Lonshi deposit, located some 35 km away in the DRC. At its peak in 2005, BMML produced just under
Ores and Concentrates The oxides from Etoile are fed into a heavy media separation plant for enrichment of copper and cobalt. This concentrate is the …
The electrolyte from the SX process is filtered to remove solids and then sent to the electro-winning (EW) plant. The EW plant operates like a large battery where metallic copper is electro-plated on to cathode starter sheets using a direct current (DC) and lead anodes. Water losses in this process occur due to: • Evaporation from the leach ...

dramatically when the Cominco (now Teck) Trail plant built a pressure leach facility for zinc concentrates (1971). This plant was a "medium" temperature process where sulfides were oxidized at 150o C and approximately 1,400 kPa using oxygen. Its' success resulted in the construction of an additional plant at the Flin Flon mine (1993).
