Tin Ore

الوصف

Tin has been known from ancient times. Ancient peoples found that heating in the tin minerals cassiterite. In the Daure Daman Juristiction Area, this peoples there are still busy with mining this very long known metal and making a living out of this. Since tin does not oxidize (rust) in air or water, it is applied to the surface of flat-rolled steel to make tin plate, which is then fabricated to produce “tin” cans. This use accounts for about one-fourth of the tin consumed annually. Alloys such as bronze and pewter are also a major use of tin. Tin is useful in electrical applications, mainly low-melting-point solders, that account for one-fourth of tin consumption. It is also used in construction, transportation (mainly in bearings requiring soft metal alloys) and other various industrial applications. For example, window glass is made by pouring molten glass onto molten tin; this process results in flat sheets of glass. An alloy of tin and niobium has proven to be a “superconducting” compound at very low temperatures.
