Refining Sulfide Metal Concentrates

Dry process for refining zinc sulfide concentrates

Methods used to obtain zinc metal from zinc sulfide concentrates are broadly divided into hydrometallurgical processes and pyrometallurgical processes. In both the hydrometallurgical processes and the pyrometallurgical processes for refining zinc, the zinc sulfide concentrates, which are the main raw materials, are first roasted to form zinc oxide.

Cadmium: processing-Metalpedia Asian Metal

Cadmium is mainly a byproduct of beneficiating and refining of zinc metal from sulfide ore concentrates. Refining of zinc and its cadmium content, can be accomplished by treating the zinc concentrates and/or zinc-bearing secondary materials using either a hydrometallurgical or pyrometallurgical process.

Nonferrous metal sulfide concentrates containing arsenic, antimony, and bismuth can be treated prior to smelting by either pyro- or hydrometallurgical routes to recover these elements as by-products. During the thermal treatment, however, a minor part of these elements will remain as an undesirable impurity in the raw nonferrous metal produced.
