Recovery of metallic tin from aqueous solution of tin salt

Example I One liter of an aqueous acidic stannous chloride solution containing 2 grams/ liter of tin is placed in the 2-liter autoclave described above. To this starting solution, which has a pH of 1.6, is added 2.82 grams of finely divided low carbon iron. This iron addition is equivalent to 3 moles of Fe for each mole of Sn in solution.

Process for recovery of indium from ITO scraps and metallurgic

Only about 15% of ITO is consumed in making TCO and the rest (85%) becomes scrap [2]. Because of the large amount of ITO scrap, a large amount of indium can be recovered. Current indium sources estimate that 65% of the indium from used ITO targets is recovered via reclaim processing [3]. ... Recovery of indium from used indium-tin oxide (ITO ...

Using tin as PM collector

Try to locate those areas, heat them and scrap this tin together and collect it. It is worth a try. Once You have 1 Kg or so, you may have it tested and see what it contains. It is very easy to melt (tin has a melting point around 230°C) and to handle. Through "migration" there may be PMs in that tin such as gold, palladium and others.

TIN RECYCLING FACTSHEET

TIN RECYCLING FACTSHEET The end-of-life destination of tin depends on the tin product. Nearly half of all tin is used in solder, with the rest split between tin chemicals such as PVC stabilisers, lead-acid batteries, tinplate, and copper alloys. Tin is typically recovered from tin manufacturing 'by-products' or 'residues'.
