A) Raffinate Pond. According to Fick's Law, increasing the copper concentration in the raffinate decreases the leaching power of the raffinate, resulting in lower copper recovery from the heap. B) PLS Pond. Typically, the acid concentration in the feed will need to be less than 5 g/L. Increased copper and acid concentrations in the SX …

solvent-extraction and electrowinning (LX/SX/EW) process has become an important option in the production of copper from low-grade oxidized ore. LX/SX/EW copper production has grown rapidly during the last decade and further growth can be expected. (Jenkins et al., 1999; Kordosky, 2002) As the copper LX/SX/EW process is relatively young

SX-EW (solvent extraction and electrowinning) are distinct metallurgical unit operations that recover high purity metal from leachate solutions. Solvent extraction is used to concentrate materials in an organic solution, while electrowinning is used to recover these pay elements. The two procedures are often conducted together.

It can be argued that adoption of SX-EW across the industry enabled the exploitation of relatively low-grade deposits (< 0.5% Cu by weight) through heap and dump leaching (Kordosky 2002) and by extension, bioleaching.Higher-grade deposits can be processed more efficiently through direct smelting or smelting of flotation concentrates.

SX/EW Plant - At the SX/EW plant, the PLS is pumped to an extraction mixer/settler tank where it is mixed with an organic solution similar to kerosene. When the organic solution mixes with the PLS, the copper is transferred to the organic solution. The mixture is allowed to settle and the copper laden organic solution floats to the top of the ...
