copper extraction refers to the methods used to obtain copper from its ores. the conversion of copper consists of a series of physical and electrochemical processes. methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.
as in all mining operations, the ore must usually be beneficiated (concentrated). the processing techniques depend on the nature of the ore. if the ore is primarily sulfide copper minerals (such as chalcopyrite), thy. j. and d. klarup, extraction kinetics of copper, zincthe ph value of the eluents is the key to control the extraction, especially to chitosan solution. it was evident that the chitosan solution was the most efficient when the ph value was 3 3.5, the rate of extraction of copper being 43.36% and of nickel being 37.07%. and the best match of concentration and liquid/solid was 0.3 g/l and 10 ml/g.an investigation into the extraction behavior of copperup to10%cash back· jul 31, 2020· in this research, solvent extraction of copper from a sulfate leaching solution containing 2083 mg/l cu and 637 mg/l fe was performed using acorga m5640 extractant diluted in kerosene. the effect of operating factors such as acorga m5640 concentration, contact time, liquor ph, and temperature on the extraction efficiency and cu/fe separation factor was
