Tin processing Britannica

2020-8-17  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 allotropic; that is, it takes on more than one form.

Two novel methods of the production of high purity

1999-9-1  1.. IntroductionComminution of tin and other soft metals using a conventional method of mechanical grinding in ball mills suffers from some technological difficulties due to the plasticity of the metals and the impurity of the powders. Other methods of soft metal attrition involve the use of additional chemicals, which also significantly worsen the purity of the powders .
