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.

Mar 22, 2021 As part of the Production Test Facility, Florence Copper will construct a Solvent Extraction/Electrowinning (SX/EW) plant that will manufacture up to 99.999% pure copper cathode. SX/EW technology was initially developed in Miami, Arizona, approximately 45 miles northeast of
The copper extracted from this process is mixed with the slag and is called Matte Copper due to its texture and appearance. This mainly consists of Cu2S which is reduced to pure metal by blasting Matte Copper with air. Cu 2 SO 2 2CuSO 2. The sulphur dioxide escapes the copper and this causes bubbles to appear and burst as SO2 leaves. This causes the final product to have a very blistery
