How is cassiterite mined?

Cassiterite is mined by dredging, hydraulic mining, or open-pit mining (Sutphin et al., 1992). Hydraulic mining utilizes a powerful jet of water to dislodge minerals from weathered deposits, while dredging extracts cassiterite from placer deposits by filtering out the heavier tin mineral from the gangue minerals.
