Zinc ore mines Iron ore, ochre mines Coal mining. Lead ore and mines Mineralisation. The lead, zinc and copper veins on Mendip were deposited by hot mineralising fluids typically between 50 and 150° C rising up from depth and depositing various minerals as they cooled. The source of the fluids were the deep sedimentary basins either side of the Mendips. As the Triassic and Jurassic

Themonly available ore used in the extraction of Zinc is called Zinc Blende also known as Zinc Sulphide ZnS. Historically extraction of zinc has been more difficult than extraction of other metals because at temperatures where metals such as iron typically begins to melt, zinc is a gas.
6.1 Process Overview 6.1.1 Lead and Zinc Ore Mining Lead and zinc ore is nearly always mined below the surface of the ground. Some veins of ore lie as deep as several thousand feet but most deposits lie close to the surface. Lead and zinc ore is mined almost exclusively in underground operations, though a few surface operations do exist. The use of underground or surface mining techniques

At first, the zinc ore is crushed in the zinc mining equipment and the zinc ore is miledl after it is moved to the crushing place. The raw material used for the production of zinc is zinc concentrate, which is the result of a flotation process after the ore has been mined and crushed.
As described in the lead zinc ore processing section, zinc sulphate and metabisulphide sphalerite and pyrite depressants, respectively, are typically added to grinding. Then a Cu Pb bulk concentrate is recovered with xanthate, dithiophosphate and flotation reagent blends.
Types of zinc ore 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 ismonly found as zinc carbonate ZnCO 3, known as calamine or smithsonite.

Zinc smelting is the process of converting zinc concentrates ores that contain zinc into pure zinc. Themon zinc concentrate processed is zinc sulfide, which is obtained by concentrating sphalerite using the froth flotation method. Secondary recycled zinc material, such as zinc oxide, is also processed with the zinc sulfide.
There are many small to medium carbonateplex zinc containing deposits where the zinc is not economically recoverable either as concentrate or metal. High grade 20 Zn run of mine ore can be processed but even this material gives relatively poor returns.

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 measures are taken to prevent it.
