zinc processing zinc processing Ores: Zinc ores are widely distributed throughout the world, although more than 40 percent of the world's output originates in North America and Australia. The common zinccontaining minerals are the zinc sulfide known as zinc blende or sphalerite (ZnS), a ferrous form of zinc blende known as marmatite [(ZnFe)S], and a zinc carbonate known as calamine .

Zinc Metallurgy Overview
The other three processes used in existing smelters account for only about 15% of global zinc production. 1. Imperial Smelting Process (ISP) uses enclosed blast furnace to treat zinc lead complex ore. Zinc vapor is released from the top of the furnace while lead is discharged from the furnace bottom.

What Is Silver Smelting? (with pictures)
Zinc concentrates that contain silver are also roasted and sulfuric acid is added to leach away the zinc. Slag fuming is then used to mix the remaining ore with coke and air to produce lead bullion in the silver smelting furnace. This lead bullion is then processed in the same way that lead ores are to produce silver, using the same type of smelting equipment.
