The zinc mining process is conducted primarily underground, with more than 80 percent of all zinc extracted beneath the Earth’s surface. Eight percent of zinc is mined in open pits, with the remaining 12 percent being mined through both methods.
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.
Also, the recovery of silver minerals occurring in a lead, zinc sulfide ore is efficiently accomplished using Flowsheet #2. The process consists of selective flotation to produce a mixed silver, lead concentrate for maximum smelter return and a separate zinc concentrate.
Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. The most common zinc concentrate processed is zinc sulfide, which is obtained by concentrating sphalerite using the froth flotation method.
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.
Ore mined is roughly crushed on site, then trucked to the Mount Isa mills for processing. First, the ore is ground into a fine dust via a series of ball mills.

Zinc Mining. The most commonly 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.

Lead and Zinc Ores Minerals of lead and zinc commonly are rather closely associated in nature; zinc-free lead ores and lead-free zinc ores are exceptional rather than common, although there are such. Lead and zinc ores usually contain some silver, but those of the Mississippi Valley region are silver-free.
Adopting mixed flotation-concentrate regrinding process can reduce the grinding cost, and be easy to manage. Application of new non-toxic flotation reagents is efficient and environmental protection.

Typically, lead and zinc ore crushing machine often used in the crushing process of lead-zinc bearing rocks. The lead and zinc grinding plant can use the ball mills, rod mills, and vertical mills. It also includeslead and zinc extraction equipment and lead and zinc refining equipment.
Gold CIL (Carbon in Leach) Process is an efficient design of extracting and recovering gold from its ore. By cyaniding and carbon leaching crushed gold ore slurry simultaneously, CIL process lower the gold mining operation cost and increase gold recovery rate to a degree of 99%.
In the hydrometallurgical process, zinc, copper and cadmium are dissolved in the sulfuric acid leach of the roasted zinc ore. The copper and cadmium are among the most common interfering impurities that are removed before the purified solution is subjected to electrolysis for zinc recovery.
