copper
In the wet process, the copper is dissolved from the ores by acids, or is converted into a water-soluble salt by roasting with a reagent. The solvent is usually sulfuric acid, hydrochloric acid, or ammonia. The acid solution containing the copper is run into tanks and the copper is precipitated by means of metallic iron or by electrolytic methods.
