copper smelting process

SMELTING ~ Technology Industry Of Gold Mining

Smelting is a form of extractive metallurgy; its main use is to the process of separating the metal from impurities by heating the concentrate to a high temperature to cause the metal to melt. Smelting the concentrate produces a metal or a high-grade metallic mixture along with a

Copper Smelting and Refining Process Pan Pacific Copper

The copper concentrates are fed through the flash smelting furnace with oxygen-enriched air. In the furnace, the concentrates are instantly oxidized, after which they melt and separate by their own reaction heat into copper matte with a grade of 65% and slag consisting of

Onahama Smelting and Refining CO.,LTD. (Smelter)

Onahama Smelter introduced Mitsubishi technology for copper smelting process. Copper concentrates(Cu 30%, Fe 25%, S 30%) is fed through lance pipe with oxygen enriched air into the smelting furnace then oxidized and melted by exothermic reaction to form molten mixture of matte(Cu 60%) and slag. All the molten materials
