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 the extraction of other metals because, at temperatures where metals such as iron typically begin to melt, zinc is a gas. Due to its very low boiling point, at such temperatures, zinc …
Zinc is mostly found in the metallic minerals associated with other metallic sulfide ore minerals, such as lead-zinc ore, copper-zinc ore, and copper-lead-zinc ore. In addition to copper, lead, and zinc, these minerals also often contain valuable metals such as silver, gold, arsenic, antimony, cadmium, indium, and germanium.

Zinc ores are recovered by many mining techniques, ranging from open-pit mining (mainly in the case of oxidized ore bodies, which are located closer to Earth's surface) to the normal underground methods (used for the more deeply located sulfide ores). The most common underground method of ore extraction is cut-and-fill stoping, in which tunnels are dug to …
The beneficiation of lead-zinc ore uses the gravity beneficiation method and flotation method, but because the flotation process is more complicated, the equipment investment is relatively large. For those concentrators that do not need to separate lead and zinc, but only need to improve the grade of lead-zinc ore, the use of the gravity …
