process of copper from sx to ew

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.

Leaching offers an alternative to copper mining. First, the ore is treated with dilute sulphuric acid. This trickles slowly down through the ore, over a period of months, dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by electrolysis. This process is known as SX-EW (solvent extraction/electrowinning).

Since copper production commenced in 2005, Sepon produced over 1 million tonnes of copper cathode. Sepon produces copper cathodes using a whole-of-ore leach, sovent extract and electrowinning (SX-EW) process. Copper Cathodes are then transported via road and sea to manufacturers of cable, wire and tube in Asia.

Sep 29, 2017 Newer plants involve copper solvent extraction-electrowinning (SX-EW), instead of direct copper electrowinning, which leads to LME Grade A copper. The copper flotation step is inefficient for cobalt, such that there is only a 40% recovery for oxides, and a maximum of 80% for sulfides. The tailings dams have significant amounts of cobalt ...
