Zine ore properties

Zinc ore is minerals including zinc element or zinc compound. Zinc is often found together with other base metals such as copper ore lead in ores. Zinc is, in some respects, chemically similar to magnesium, because its ion is of similar size and its only common oxidation state is +2. Zinc is the 24th most abundant element in the Earth’s crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest mineable amounts are found in Australia, Asia, and the United States. Zinc production includes froth flotation of the ore,roasting, and final extraction using electricity (electrowinning).

Zinc ore application

Zinc is the fourth most common metal in use, trailing only iron, aluminium, and copper with an annual production of about 12 million tonnes.  About 70% of the world’s zinc originates from mining, while the remaining 30% comes from recycling secondary zinc. Commercially pure zinc is known as Special High Grade, often abbreviated SHG, and is 99.995% pure. Worldwide, 95% of the zinc is mined from sulfidic ore deposits, in which sphalerite ZnS is nearly always mixed with the sulfides of copper, lead and iron. There are zinc mines throughout the world, with the main mining areas being China, Australia and Peru. China produced 29% of the global zinc output in 2010.
Zinc metal is produced using extractive metallurgy. After grinding the ore, froth flotation, which selectively separates minerals fromgangue by taking advantage of differences in their hydrophobicity, is used to get an ore concentrate. A final concentration of zinc of about 50% is reached by this process with the remainder of the concentrate being sulfur (32%), iron (13%), and SiO2(5%).

Zinc ore production processing and equipment

SBM machinery is a global manufacturer and supplier of technology and services for mining and beneficiation equipment. We could provide complete sets of zinc ore processing equipment, including jaw crusher for primary crushing, impact crusher for secondary crushing, vibrating screen and feeder, belt conveyor, grinding mill, mobile crusher etc. Of these machineries, zinc ore grinding mill can produce even and fine final products. Mobile zinc ore crusher has high crushing ratio and produce even finished particles.

Jaw crusher is the most common and often used zinc ore crushing equipment, zinc jaw crusher can achieve crushing ratio of 4-6. Zinc jaw crusher can break the raw zinc ore materials into 150mm or 6 inch size particles, these particles are conveyed by belt conveyor to vibrating screen, the unqualified zinc particles will be conveyed for secondary crushing process. Impact crusher and cone crusher is the common used equipment in secondary crushing process.
Just contact us about your requirements, we will provide your best solution, and wish our considerate service could bring you unexpected wealth.
