Kasiterit tin (SnO2)

TIN (Sn)

Tin is a silvery white metal, is relatively soft, corrosion resistant and has a low melting point. Tin present in 2 forms allotropes of tin and gray tin. The most important tin ore is kasiterit (SnO2). Place tin ore mining in Indonesia is on Bangka, Belitung and island-Riau.w Kampar
The process of formation of tin:
  SnO2 (s) 2C (s)
  Sn (l) 2CO (g)

Use of Tin
1. To make cans (team plate) range of products.
2. Surfacing tebuat cans of iron that will protect iron from perkaratan.
3. Make a mix of metal, such as bronze (alloy of tin, copper, zinc) and solder (tin and lead alloy)
Tin processing

Tin ore after then baked so that the arsenic was concentrated and separated in the form of sulfur oxides that easily evaporate. Then the tin ore that has been purified it is reduced with carbon. Tin liquid collected in the bottom of the furnace and then poured into molds to obtain tin bar. Tin is still quite rough and needs to Purify. Purification of tin can be done in 2 stages:
1. HIGH TENTION SEPARATOR
Mineral terpusah style electricity such as tin, iron.

2.MAGNETE SEPARATOR
Minerals are not interested in tin, tin ore ready for smelting process to obtain pure tin.
