The copper-bearing solution, from the solvent extraction operations, is plated into pure copper cathodes using a process called solution exchange electrowinning (SX-EW). Stainless steel blanks are added to the plating tanks to act as cathodes and copper is plated onto them by Beginning in the mid 1980s a new technology, commonly known as the leach-solvent extraction-electrowinning process or, SX/EW Process, was widely adopted. This new copper technology utilizes smelter acid to produce copper from oxidized ores and mine wastes. Today, worldwide, approximately 20% of all copper produced is produced by this is process.

4. Beneficiation of Copper Ore. The next step in processing is called beneficiation. This is the first step in concentrating the copper into a more useable form. 5. Smelting and Extraction. The next step in the process flow is smelting for sulfide ore concentrate and solvent extraction for oxide ore leach solution. 6. Extraction and refining. The extraction of copper from ore is normally carried out in three major steps. The first step, mineral processing, is to liberate the copper minerals and remove waste constituentssuch as alumina, limestone, pyrite, and silicaso that the copper minerals and other nonferrous minerals of value are concentrated into a product containing between 20 and 30 percent
