Hardness: 2

Composition: zincite, ZnO2, and smithsonite, ZnCO3

Special quality: Opaque, metallic

Place of origin: China, Australia

Functional use: Zinc is widely used in paints, for coating steel, automotive parts, electrical fuses, batteries, roof gutters, pennies, rubber, deodorant, and much more.

Zinc ore characteristic

Zinc ore usually is found in association with those of lead, copper, gold, silver as well as other metals. Zinc is found in igneous and metamorphic rocks which usually are underground, so zinc mining is often underground but some new mines are of the open pit type. While 21% of mine production comes from the combination of underground and open pit mining.

Zinc mining

At first, zinc ore is crushed in the zinc ore crusher and zinc ore mill 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 is drilled and blasted in large volumes, transferred to underground rock crushers by large loaders and trucks before being hoisted to the surface in skips or driven directly to the surface by truck via a spiral access tunnel called a decline. At the surface, the ore is subjected to additional crushing and fine grinding. The flotation process is then used to separate the zinc and other valuable sulphide minerals from the waste rock particles or tailings to form a concentrate.

The iron and zinc oxides that, after the crushing and roasting process, have been reduced to powder form, are leached with dilute sulphuric acid. The solution is neutralised and the precipitates i.e. metallic co-products together with any unwanted contaminants, are removed by filtration.

Zinc ore crushing

The crushing of zinc ore is widely used in the process of materials. Zinc ore crushers achieve the primary crushing process. To most of the ores process, zinc ore crushers are enough. But for the fully chemical reacting, zinc mills are often used for thin crushing. Although the zinc mining often happens underground, the crushing of zinc ore is going along upgroud. Zinc ore crusher is widely used in China, Australia, Peru, Canada, and the U.S.
