Zinc: smelting, producing and classification-Metalpedia
Zinc: smelting; Zinc Mining; 80% of zinc mines are underground, 8% are of the open pit type and the remainder is a combination of both However, in terms of production volume, open pit mines account for as much as 15%, underground mines produce 64% and 21% of mine production comes from the combined underground and open pit mining
plants susceptibility to injury by high light or temperature intensity and to infection by fungal diseases can also increase [11,12] Zinc seems to affect the capacity for water uptake and transport in plants and also reduce the adverse effects of short periods of heat and salt stress [13,14,15,16]
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 .
