Solvent extraction of zinc from zinc sulfate solution

The studies about solvent extraction of zinc from sulfate solution were mostly carried out on the background of removing trace impurity zinc [6−7]. Because of the lack of effective zinc extraction reagents and relatively low prices of zinc metal, the applications of solvent extraction of zinc from sulfate solution are limited [8−9].

Extractive Metallurgy Presentation (Zinc)

Electrolysis Zinc is extracted from the purified zinc sulfate solution by electrowinning, which is a specialized form of electrolysis. Working: The process works by passing an electric current through the solution in a series of cells. This causes the zinc to deposits on the cathodes (aluminum sheets) and oxygen to form at the anodes.

The Properties and Uses of Zinc Metal

Zinc (Zn) is an abundant metal, found in the Earth's crust, with a myriad of industrial and biological uses. At room temperature, zinc is brittle and blue-white in color, but it can be polished to a bright finish. A base metal, zinc is primarily used to galvanize steel, a process that protects the metal against unwanted corrosion.

Zinc smelting - Wikipedia

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 ...

The principal ore of zinc used for its extraction is Zinc blend ( Z n S). As Zinc blend is a sulphide ore, the process used for its concentration is the Froth Floatation Method. The concentrated ore is then roasted in excess air at 1200 K to obtain zinc oxide ( Z n O). It is then reduced to Z n by coke at a temperature of 1673 K.
