2017.8.21 There are more than 50 kinds of tin-bearing minerals on Earth; among them, cassiterite (SnO 2) is the only natural mineral from which tin metal can be economically extracted.1,2,5 Because of its high relative density, cassiterite is easily beneficiated from placer/alluvial tin deposits through a gravity separation process,1,2

Extraction of Tin/ Stannum. Extraction of tin consists of three parts, i.e. tin ore concentration, smelting and refining. Cassiterite is the main source of tin ore, with specific gravity of 6.8-7g/cm 3, density larger than most of gangue. Therefore, 90% of tin concentrate is mainly obtained from cassiterite through gravity separation.

gaining tin metal is the separation of tin from iron due to the high temperature of smelting. The smelting conditions should be such that the tin oxide is reduced to the metallic state while iron oxide is reduced to lower oxide (the ferrous oxide) and passes into the slag.

The DDDF separation and recovery process is shown in Scheme 1. The process can be divided into four steps: dissolution, distillation or crystallization, dehydration, and fractionation. First, the spent ITO powder was dissolved completely with HCl, and then the leached solution was distilled to obtain the crystal of metal chloride hydrates.

Suppose you have a mixture of 67% lead and 33% tin. That's the mixture from the first cooling curve plotted above. Suppose it is at a temperature of 300°C. That corresponds to a set of conditions in the area of the phase diagram labeled as molten tin and lead. Now consider what happens if you cool that mixture.
