Sources and mines of Zinc

Zn is found in many countries in the world and there are about 50 mines in the world. China, Australia, Peru, Europe and Canada are among the largest zinc mines. In nature, two elements of lead and zinc often come together. Nearly 70 percent of the lead is produced from lead-zinc ore minerals, which normally contains zinc in anhydrous than crude. Nearly 20% of lead production is associated with mixed minerals with a higher lead content and 10% of lead production in relation to copper minerals.
Lead and zinc minerals are often found in mixtures and deposits. The main deposits of these two metals are hydrothermal, epithermal, mesothermal and tetrameric. In zoological deposits, zinc is usually greater. Depending on the type of placement of lead in gaps and joints, accumulated groups in which the lead in the hydrothermal solution is converted into insoluble matter due to chemical interactions, and the gaps and gaps are accumulated, and the successor in which The lead ion in the hydrothermal solution is replaced by the metal ions in the surrounding rocks, and for example, it converts calcium or lime carbonate into lead carbonate.
The lead and zinc sulfides in the upper part of the deposits are affected by the weather, altered, and converted to the oxide minerals of this metal. It should be noted that the sphalerite is altered sooner than gallon. Trapped masses are commonly found in calcareous soils in areas where there are no hydrothermal streaks. At the site of these masses, recrystallization of calcite and dolomite is observed, and sometimes some of the gypsum and baritin are combined with ore, sometimes lime is slightly silica in these deposits. The tetrameric deposits are usually substitutions.
Zinc is commonly found in sulfide and most of the time comes from the source of hydrothermal fluids and sialic and cymful magmas. Sedimentary deposits are less important. Some of the deposits formed in carbonates have the properties of marine sediment deposits. Although in these deposits, it can be assumed that the metal is provided with a hydrothermal transfer of game magmas in this way. Mineral crystal is obtained from a hydrothermal solution in the form of pure zinc sulfide. Mineral marmaris is a complex combination of iron and zinc in the form of sulfide, which is found abundantly but rarely extracted. Because it is difficult to clean it.
Reservoirs close to the Earth's surface are often converted to oxide or carbonate, smaller zinc carbonate masses are known as silicate hydrates or hemimorphic mines. Iron and lead sulfides are found in the form of mineral pyrites and galena (mineral lead) in large masses, while other metals are rarely inorganic in nature. Mineral zinc is a metamorphic zinc oxide (changed state), such as Franklinite or Zinc catalyst, in small amounts and in limited locations.
Zinc utilized accumulations are found in various geological environments. These aggregates are geographically divided into the following segments according to the conditions of occurrence:
1- accumulated mass sulfurs from submarine eruptions in sedimentary rocks,
2. Cumulative stony deposits in carbonate rocks,
3. Crushed stones in sandstone,
4. Stomach cramps
5. Metamorphic accumulation
