Dec 07, 1982· The copper is recovered from the solvent by stripping in 3 stages with return electrolyte from electrowinning, containing 30 g Cu/L and 150 g H 2 SO 4 /L, at an O/A ratio of 6 and with a retention time in the mixer of 1 min. Sulphate remaining on the solvent after stripping is removed in 3 stages of water scrubbing at an O/A of 8 for 1 min, and the solvent recycled.

Copper processing, the extraction of copper from its ores and the preparation of copper metal or chemical compounds for use in various products. In its pure form or as an alloy, copper (Cu) is one of the most important metals in society.
1. Flow diagram of the copper solvent extraction process. In the extractionunit,thecopperitractedfromthepregnantleachsolution (PLS) to the organic solution. The raffinate solution (Raff) is recycled. The copper is stripped from the loaded organic solution (LO) to lean electrolyte (LE) in the stripping unit.
Copper hydrometallurgy is a branch of metallurgy method to extract copper directly from those difficulttoconcentrate copper oxide ore. Traditional copper hydrometallurgy process typically consists of atmospheric leaching, solvent extraction (SX) and electrowinning (EW).

: Solvent Extraction and Separation of Copper and Zinc from a Pickling Solution . During extraction of metals using acidic extractants, H + ions are released causing the decrease in pH which subsequently lowers extraction of metals in several instances. So the extraction process is .
Froth flotation. Such carbonate concentrates can be treated by a solvent extraction and electrowinning (SXEW) plant or smelted. The copper ore is crushed and ground to a size such that an acceptably high degree of liberation has occurred between the copper sulfide ore minerals and the gangue minerals.
In the stripping step, an aqueous solution with a high concentration of sulfuric acid is used to strip the copper from the organic back into solution (transfer from chemical copper back to ionic copper). This is the reverse of the extraction step. Both the extraction and stripping step occur at the SX Plant.
Solvent Extraction of Copper: An Extractive Metallurgy Exercise for Undergraduate Teaching Laboratories
Fig. 1. Flow diagram of the copper solvent extraction process. In the extraction units, copper is extracted from the pregnant leach solution to the organic solution. In the stripping units, copper is stripped from the loaded organic solution to the electrolyte solution. The resulting rich electrolyte solution is led to the electrowinning process.
