Copper Solvent Extraction Process

chapter 6 copper production technology,for producing copper, from exploration, through mining and milling, to smelting and refining or solvent extraction and electrowinning. the chap-ter begins with an overview of the history of cop-per technology development. then, for each stage i n copper production, it reviews the cur-rent state-of-the-art, identifies recent technologi-.process of solvent extraction of copper sumitomo metal,the process of the present invention treats an aqueous chloride solution containing copper and one or more concomitant elements to recover copper by separating it from the concomitant elements, comprising a step for selective extraction of copper from the aqueous chloride solution by mixing the solution with an extractant of organic solvent.
