Improving base metal electrowinning

In copper electrowinning, the effects of temperature, power outages and concentrations of cobalt and manganese on anode corrosion and current efficiency have not been well investigated. Benchscale tests were used to investigate these effects. Anode corrosion in all experiments was minimal probably due to the presence of at least 150 mg/L

IsaKidd refining technology - Wikipedia

The process used involves leaching the copper from the material using an acidic chloride–sulfate solution, followed by solvent extraction to concentrate the leached copper and electrowinning. Electrowinning copper differs from electrorefining in that electrorefining uses a copper anode that is dissolved and redeposited on the cathode, while in electrowinning the copper is already in solution and

Major Mines & Projects | Antucoya Mine

Mined oxide ore is crushed, piled into heaps and then leached with sulphuric acid, producing a copper sulphate solution. This solution is then put through a solvent extraction and electrowinning (“SX-EW”) plant to produce copper cathodes, which are sold to fabricators around the world.

Trade misinvoicing in copper products: a case study of Chile

of the 5.76 million metric tons (mt) of fine copper that Chile produced in that year, 3.99 million mt were copper concentrates and 1.78 million mt were refined cathodes produced by means of solvent extraction/electrowinning. Some of the concentrates were electrolytically refined to produce copper cathodes (910,000 mt) and other smelted products.

SX-EW (solvent extraction and electrowinning) | KGHM

SX-EW technology involves leaching (the process of dissolving useful ingredients with a solution) in atmospheric conditions of copper ore heaps by means of diluted sulphuric acid. Folowing leaching, the pregnant leaching solution is transported via a drainage system to the next stage. In an SX-EW reactor, the first process to take place is solvent extraction, which involves setting and
