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.

Development of copper recovery process from flotation …
Stevanović et al. [61] investigated a hydrometallurgical process for copper revalorization from overburden of abandoned mine Cerovo in Eastern Serbia using percolation leaching, followed by solvent extraction (SX) and electrowinning (EW) processes. They found that copper recoveries through leaching, SX, and EW processes …
How can you increase the copper recovery of your SX-EW …
The steps are as follows: 1) LEACH. Low grade copper ore is leached, producing solid waste and copper PLS. 2) EXTRACTION. The copper PLS is sent for extraction where the copper is loaded into the organic phase, leaving a copper-barren leach liquor (raffinate) to be recycled back to the heap leach. 3) STRIPPING.
