Cassiterite - Wikipedia

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.

% tin of the cassiterite was not converted into Na2SnO3 and entered the leach residues. Most of tin in cassiterite is in shape of crystals with high single separation degree and big density, so gravity separation is a great enrichment way to get high-grade tin concentrate. The cassiterite rich slurry is further concentrated by gravity separation methods, which involve flushing the slurry with ...

As the slurry flows along, the heavier minerals, including cassiterite, fall to the bottom, while the lighter waste material flows over the end of the boxes to tailings dumps. Periodically the flow is stopped and the crude concentrate removed.
