Dissolved copper from the anode is electrolytically deposited on the stainless steel cathode plate. After about 10 days of electrolysis, the cathode is lifted out and stripped from the stainless steel plate, resulting in the completion of refined copper (with grade of 99.99%) as a final product.

Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.

Copper production begins with the extraction of copper-bearing ores in mining or recycling of scrap metal. The ores are processed into copper concentrate, which can be further treated onsite or sold to a smelter. The figures below represent global production and trade of copper contained within ores and concentrates (ICSG, 2015).
