Zinc mining

Zinc mining is the process by which mineral forms of the metal zinc are extracted from the earth through miningA zinc mine is a mine that produces zinc minerals in ore as its primary product Common co-products in zinc ores include minerals of lead and silver Other mines may produce zinc minerals as a by-product of the production of ores containing more valuable minerals or metals such...

Zinc ore and mines Minerals and mines Foundations of

Zinc ore occurs in two types of deposit as primary zinc ore in thin veins known as rakes or a secondary deposit formed by weathering of the primary mineral veins Zinc ore is most commonly found as zinc carbonate ZnCO 3 known as calamine or smithsonite It generally occurs as rounded crystalline crusts or granular honeycombed masses that...

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 eg iron because in contrast zinc has a low boiling pointAt 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...
