Zinc smelting Wikipedia

2020-05-02· 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

Refining (metallurgy) Wikipedia

2020-05-02· In metallurgy, refining consists of purifying an impure metal. It is to be distinguished from other processes such as smelting and calcining in that those two involve a stone change to the raw material, whereas in refining, the final material is usually identical chemically to the original one, only it is purer. The processes used are of many types, including pyrometallurgical and

Zinc treatment, refining charges seen high on rising mine

Spot TCs,or fees that miners pay smelters to process zinc ore into refined metal, have climbed relentlessly in 2019 to an 11-year high of $290 a tonne, as fast-rising mine supply overwhelms limited smelting capacity. The more than a decade-high TC "is a strong incentive for zinc smelters to produce as much metal as they can," Hobbs said.
