Solvent Extraction & Electrowinning (SX/EW) Plant Design

The SX plant was built with four parallel trains each having three extraction and two stripping mixersettlers The total flow capacity Solvent extraction and electrowinning ( SX/EW) is a twostage hydrometallurgical process that first extracts and upgrades copper ions from lowgrade leach solutions into a solvent Solvent extraction and electrowinning

SX EW Capital & Operating Cost of Solvent Extraction

solvent extractionelectrowinning (SXEW) is one possible way to economically extract copper from ore bodies which cannot otherwise be profitably exploited Published costs for the unit processes of SX and Electrowinning power requirement has been reported to be equal to 21 MWh per ton copper by Sole and Tinkler (2015)Alvarado et al (2002) have estimated that the SX/EW process consumes around 27Operating copper SX EW plants and nearterm projects

Copper SXEW What are the options?

SXCopper Sulphate The main advantage is the replacement of the capital and power intensive EW step by copper sulphate production from the SX loaded strip solution However, the cost ofThe benefit of using emew in an SXEW plant is for increased copper recovery to decrease the recirculating copper load A direct result of electrowinning the copper is a concurrent increase in acid How can you increase the copper recovery of your SXEW

Innovations: How Hydrometallurgy and the SX/EW

The SX/EW Process is a hydrometallurgical process since it operates at ambient temperatures and the copper is in either an aqueous environment or an organic environment during its processing until it is reduced to the SXEW (solvent extractionelectrowinning) is the cathode copper production technology used in the KGHM International facilities SXEW technology involves leaching (the process of dissolving useful ingredients with a solution) in atmospheric conditions of copper ore heaps by means of diluted sulphuric acidSXEW (solvent extraction and electrowinning) KGHM
