SX EW Capital & Operating Cost of Solvent Extraction & Electrowinning
As a result each mixer settler is ½ the size of those in the 2×1 circuit and the total settler area is only 66.7% of that of the 2×1 circuit. The cost saving is estimated to be about 29% which gives a capital cost of $5.0 million. The electrowinning capital cost is the same for each plant and is based on a copper production of 27.2 tonnes/day.
