Tin processing Britannica

Tin processing, preparation of the ore for use in various products. Tin (Sn) is a relatively soft and ductile metal with a silvery white colour. It has a density of 7.29 grams per cubic centimetre, a low melting point of 231.88 °C (449.38 °F), and a high boiling point of 2,625 °C (4,757 °F). Tin is

Tin processing - Mining and concentrating Britannica

The tin melts slowly and runs down the slope, to be collected in a vessel, leaving the unmelted residues on the hearth. These are subsequently removed and treated. Vacuum distillation is sometimes used in fire refining. In this process, molten tin is heated in a dense graphite vessel at high temperatures (1,100 to 1,300 °C, or 2,000 to 2,375 ...

Refining Tin - ChestofBooks

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 1/4 and 16 1/2 per cent., while the latter rauges from 1/4 to 10 per cent. The refining may be divided into 2 stages, liquation and tossing. For the liquation, the ...

Sustainable Production - International Tin Association

Tin Smelting and Refining. Once a tin concentrate of the required purity has been obtained (55 to 75% SnO2), it is sent to a smelter who smelts it into crude tin metal by removing the oxygen from the mineral. Many unwanted impurities are removed in the slag during this process, but additional remaining impurities are treated in the refining step (e.g. by heating under particular conditions in ...
