1 - GOLD
Gold is leached with cyanide. facilitates the use of cyanide oxidation forming gold Au (CN) 22 - in the solution. THE principal applies mind gold in jewelry, medicine for rheumatic disease treatment and kidney. It is also used for the electrical industry.
2 - SILVER
metallurgy from its ores is carried out mainly by cyanidation
70% of the production is used for industrial purposes and the remaining 30% for monetary purposes, much of this metal is used in jewelry. But its most important use is the photographic industry, chemistry, medicine, and electronics.
3 - LEAD
Wider use of lead, as such, is in the manufacture of batteries . Other applications include the manufacture of tetraethyl lead , cable liners , construction elements , pigments, soft solder , ammunition , fishing weights.
4 - COPPER
Copper is derived from sulphide ores (80%) and oxide ores (20%), the first are treated by a process called pyrometallurgical and second by another process called hydrometallurgy. Copper and its alloys allow certain heat treatments for very specific purposes, the most common being the annealing, refining and tempering. The main pure copper used in manufacturing mind power cables, industrial, telecommunications, transport, construction and decoration, coins and musical instruments.
5 -ZINC
The main application is the zinc galvanized steel for corrosion protection. It also applies in batteries, injection molded parts in the automotive industry, used in oil paintings manufacturing, metallurgy of precious metals and removal of silver from lead.
Zinc production begins with the extraction of mineral that can be both open pit and in underground deposits. Minerals extracted subsequently crushed and subjected to a flotation process to obtain the concentrate.
6 - IRON
It is the most used metal harder. The iron has a great application to make steel products. From the get steel, which is imperative because of its low price and toughness, especially in cars, boats and edificios.se structural components extracted by combustion and desulfurization methods.
7- MG
Used as refractory material in furnace for iron and steel production, as well as agriculture and chemical industries and construction. The metal is obtained by principal mind magnesium chloride electrolysis method is already used Robert Bunsen.
8- FLUORITE
The main use of fluorite is hydrofluoric acid production. Other applications are in metallurgy, chemical industry and special optics. The largest mine in the world is Mexico em in in a state of San Luis Potosi.
