An improved hydrometallurgical process for the recovery of metallic copper, elemental sulfur, compounds of molybdenum and other valuable materials from copper sulfide ore concentrates, such as chalcopyrite. The process, comprising a reduction stage, metallic copper recovery stage, and a combined regeneration-purge-oxidation stage, is improved by the addition of a second reduction stage following the first or primary reduction stage, and by the addition of a by-product recovery stage after the second or secondary reduction stage. The secondary reduction stage also enhances overall process performance by allowing more flexible operating practices.
