Copper Blast Furnace Smelting-Copper-

Blast furnace has been used for iron/copper/copper-nickel/zinc/lead and zinc-lead complex concentrate smelting for a long time. It plays a fundamental role to modern metallurgy and is still very important in the small-scale smelting application.

Zinc Blast Furnace Smelting-Zinc- - Metalcess

Zinc smelting with blast furnace is also named as Imperial Smelting Process (short form as ISP). ISP furnace can smelting the lead-zinc mixing concentrate, residue from zinc concentrate leaching and Crude Zinc Oxide (C.Z.O.) from EAF dust etc. to produce lead bullion and crude zinc at the same time.

2013-7-18  In practice, due to a lower slag volume and improved gas-slag contact a higher overall recovery of zinc is obtained. Future operations are likely to emphasize the role of the furnace as a combined zinc-lead-copper producer and consideration is given to the influence of the copper content of lead bullion on the copper solubility in slag.
