preparing zinc ore for smelting
How To Smelt Metals At Home
So the U.S. Mint started making pennies out of cheaper zinc, and coating them with copper to make them look like copper. Apparently 1982 was a transitional year, and all pennies dated 1983 or later are composed mostly of zinc. ... We call this special process smelting. Malachite is an ore of copper, and you can smelt copper by baking ground ...

Lead and Zinc Smelting
Zinc Manufacturing. In the most common hydrometallurgical process for zinc manufacturing, the ore is leached with sulfuric acid to extract the lead/zinc. These pro-cesses can operate at atmospheric pressure or as pressure leach circuits. Lead/zinc is recovered from solution by electrowinning, a process simi-lar to electrolytic refining.
