Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point.At temperatures typically used for smelting metals, zinc is a gas that will escape from a furnace with the flue gas and be lost, unless specific

ground ore with oil and gently pushed the pulp onto the surface of d1e \.Vater. The tubes were first com­ mercially installed in 1906 in the Adelaide Mill at Golconda, Nevada. In 1911, the Morning Mine near Mullen, Idaho used the process on lead-zinc ores in its mill. Because the process was extremely fragile, its use was short-lived.

Copper Ore Processing Methods

The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger
