Cassiterite Mineral Properties Used as an Ore of Tin

CompositionDistributionGeologyAvailabilityPropertiesMost of the worlds cassiterite is produced from secondary, placer deposits. These are sediment-hosted concentrations of cassiterite in stream valleys and along shorelines. The hardness of cassiterite enables it to survive stream transport, and its high specific gravity causes it to concentrate in deposits that are large enough and rich enough for mining. Other high-specific-gravity minerals might also occur in these deposits, improving the economy of mining. Placer deposits of cassiterite are being worked today in Bu

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.

Mineral processing Concentration Britannica

Mineral processing Mineral processing Concentration: Concentration involves the separation of valuable minerals from the other raw materials received from the grinding mill. In large-scale operations this is accomplished by taking advantage of the different properties of the minerals to be separated.

Cassiterite is chemically resistant, heavy and readily forms residual concentrations. These concentrations may develop over a primary deposit (eluvial) and on slopes below the deposit (colluvial). When the cassiterite reaches a drainage system, it may be transported to a river channel and concentrated into an alluvial placer deposit.
