Extraction and Separation of Tin from Tin-Bearing Secondary
Based on the relationship between ionic radius and electronegativity, isomorphic replacement between Sn 2+ /Fe 2+ and Sn 4+ /Fe 3+ easily occurs; hence, tin is regarded as a siderophile element according to Goldschmidt's rules.1,7,8 Therefore, cassiterite is always associated with iron-bearing minerals. Tin-bearing magnetite-skarn …Web
