Copper Processing Roasting Smelting And Converting

The final step consists of fire refining the blister copper to reduce the sulfur and oxygen to even lower levels this oxidationreduction process is usually carried out in a separate furnace to ensure that the final smelter product reaches the level of 995 percent copper that is required for electrolytic refining

Copperextraction And Purification Chemguide

The copper ii ions in the chalcopyrite are reduced to copper i sulphide which is reduced further to copper metal in the final stage the iron in the chalcopyrite ends up converted into an iron ii silicate slag which is removed most of the sulphur in the chalcopyrite turns into sulphur dioxide gas

Copper Mining And Processing Everything You Need To Know

Mined from open pits copper ore must be crushed as part of the process that occurs between extraction and production using todays compact mining equipment copper ore is extracted from the mine after the ore is crushed its roasted which helps to convert sulfides to oxides the oxides are smelted to produce matte which then undergoes several refining processes what is copper used for water
