Copper Smelting
smelting operations. At power costs in the range of 5 -6¢lkWh, there are savings in the cost of energy to the smelting furnace by using oxygen enrichment. At higher power prices, the fuel-fired flash smelting processes probably retain some advantage, whereas in some of the other processes, the cost of savings will decrease.

What Is Smelting Plant?
Smelting is a form of extractive metallurgy to produce a metal from its ore. Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gasses or slag and leaving just the metal behind. The reducing agent is commonly a source of carbon such as coke, charcoal, and coal.
Copper Smelting and Refining Process | Pan Pacific Copper
The matte produced by the flash smelting furnace is transferred to the Converter furnace. Oxygen-enriched air is blown into the Converter furnace to oxidize the matte further to create blister copper with a grade of approximately 99%. Reaction in the converter. Cu 2 S・FeS + SiO 2 + O 2 → Cu + 2FeO・SiO 2 + SO 2 + Reaction heat.
