Smelting and Refining

Primary smelting and refining produces metals directly from ore concentrates, while secondary smelting and refining produces metals from scrap and process waste. Scrap includes bits and pieces of metal parts, bars, turnings, sheets and wire that are off-specification or worn-out but are capable of being recycled (see the article "Metal reclamation" in this chapter).Nickel Processing | Nickel | SmeltingDrying Concentrates and sand used as flux are dried to reduce the moisture content from 7 8 % to about 0.2 % prior to smelting process. 5.
