Cassiterite mineral Britannica

Cassiterite, also called tinstone, heavy, metallic, hard tin dioxide (SnO 2) that is the major ore of tin. It is colourless when pure, but brown or black when iron impurities are present. Commercially important quantities occur in placer deposits, but cassiterite also occurs in granite and pegmatites. Early in the 15th century, the cassiterite veins in Saxony and Bohemia were mined for tin ...
