Cassiterite: Mineral information, data and localities.

The primary ore of Tin, this mineral is found in hydrothermal veins and pegmatites associated with granite intrusions. Because of its durability, it is also frequently found concentrated in alluvial placer deposits, sometimes in large enough quantities to be commercially exploitable, as in Malaysia, for example.

Economic Geology of Niobium and Tantalum

Tantalum ore has characteristically grades of about 0.03% Ta 2 O 5, generally as a co-product of cassiterite and other minerals. Note that because of facile overgrinding, metallurgical recovery of columbite by crushing and milling hard-rock ore is often as low as 50%. Tantalum is silvery grey, heavy and very hard but malleable and ductile.

Tests showed that Alabama tantalum concentrates with 22 to 29% SnO2 can be magnetically upgraded. As much as 78% of the tin was removed during magnetic separation. The resulting cassiterite byproduct contained 70 to 74% SnO2. The magnetic tantalum product contained 54 to 60% Ta2O5, 9 to 11% Nb2O5, and 10 to 12% SnO2.
