  • Cassiterite - Wikipedia

    OverviewOccurrenceCrystallographyEtymology

    Most sources of cassiterite today are found in alluvial or placer deposits containing the resistant weathered grains. The best sources of primary cassiterite are found in the tin mines of Bolivia, where it is found in hydrothermal veins. Rwanda has a nascent cassiterite mining industry. Fighting over cassiterite deposits (particularly in Walikale) is a major cause of the conflict waged in eastern parts of the Democratic Republic of the Congo. This has led to cassiterite being considered a conflict mineral.

  • Cassiterite from Cornwall

    Cassiterite is a tetragonal oxide, with specific gravity 6.8-7.1. Being so dense, the dark oxide grains, when eroded from primary mineral deposits, form placers (heavy mineral sands), and so can be panned or sluiced from well-situated alluvial deposits, in the same manner as placer gold or platinum. Agricola, in his De Re Metallica, described no less than eight ways by which black tin ore ...
