What is an SX/EW plant? | Florence Copper

Mar 24, 2016· SX/EW technology was initially developed in Miami, Arizona, approximately 45 miles northeast of Florence, and several SX/EW facilities are scattered throughout Arizona today. Once copper laden solution, also known as pregnant leach solution (PLS) is recovered from wells on the Florence Copper property, it goes for processing at the SX/EW plant.

Major Mines Projects | Tenke Fungurume Mine

Copper is extracted using standard SAG milling, sulphuric acid leach, SXEW to produce copper cathode. Iron, manganese and aluminium are removed from a low grade residue stream from the tankhouse and a cobalt rich solution is recovered which is purified before the cobalt hydroxide product is precipitated out.

The change from direct electrowinning to SXEW flowsheets means that the concentration of cobalt in the bleed stream and hence the cobalt purification section is significantly lower. Typically, the concentration of cobalt has reduced from the range of 10 to 20 g/L with direct electrowinning to the range of 2–5 g/L with copper SX.
