(PDF) Pyrometallurgical Extraction of Tin Metal from the …
There are many industrial techniques for tin extraction from its ores depending on the type of the ore itself, oxidic or sulfide. Each type of the ore should be treated by the suitable technique according to its chemical composition. [2,6] Tin is extracted from oxidic ores usually by reduction smelting of the ore at high temperature (›1200 ...
Formation of tin ore deposits: A reassessment
Tin granite subintrusions reach average primary tin levels of around 30 ppm. The hydrothermal depletion of a tin-enriched magmatic system must therefore comprise a large rock volume of up to 40 km 3, when an extraction rate of one third (10 ppm Sn) is assumed. The whole magmatic fractionation system must be at least ten times larger in …
