Refining Tin The crude metal obtained by the smelting whether in the reverberatory or in the blast furnace has to undergo a refining process. The two chief impurities are iron and lead the former of which may vary between 1 14 and 16 12 per cent. while the latter rauges from 14 to 10 per cent
The soldering tin mainly contains lead and tin can be refined by vacuum distillation furnace. Metalcess uses multiple

Usually the operation is carried out as a batch process. The principle of tin smelting is the chemical reduction of tin oxide by heating with carbon to produce tin metal and carbon dioxide gas. In practice the furnace feed contains the tin oxide concentrate carbon in the form of anthracite coal or coke

If the plant is meant to produce soft Lead the crude Lead must undergo a refining process. The objective of the refining process is to remove almost all copper Cu antimony Sb arsenic As and tin Sn since soft Lead are not allowed to have more than 10g per ton of these metals.

Tin concentrate is then smelted by heating it in the presence of carbon to 1200 1300 degrees centigrade reducing the cassiterite to tin metal and releasing carbon dioxide. Following the smelting process to produce tin metal the remaining impurities are removed through a refining process usually at a facility co
