The latter operation produces finished copper concentrate, finished pyrite concentrate, and middlings which are re-treated.". The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining.
