Zinc smelting

Zinc smelting

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

Leaching (metallurgy)

Leaching (metallurgy)

Leaching is a process widely used in extractive metallurgy where ore is treated with chemicals to convert the valuable metals within into soluble salts while impurity remain insoluble.These can then be washed out and processed to give the pure metal; the material left over is commonly referred to as tailings.Compared to pyrometallurgy leaching is easier to perform, requires less energy and is

Extraction of Zinc from Smithsonite by Ammonia Leaching

Extraction of Zinc from Smithsonite by Ammonia Leaching

The aim of the study was extraction of zinc from smithsonite by ammonia leaching on cerussite flotation tailings. Initial lead and zinc grades of the ore were 13.31% and 27.86%, respectively. As a result of a series of cerussite flotation tests, a lead concentrate containing 63.25% Pb was produced with 82.76% recovery. After that,
