recoverable” tin as at such low grades the use of fines recovery methods such as centrifugal and flotation is not practical and cannot be economic. Fine tin loss is academic as could not recover any way • Kg of Tin per Cubic Metre is the preferred unit adopted now. • Note that the assay is sometimes given as Cassiterite (SnO2) not Tin
Tin is not widely distributed and is really a semiprecious metal. Tin hardly ever occurs "native" as metal. Its only re ally significant ore is cassiterite (Sn02), which is normally a dull drab brown material that is difficult to distinguish from ordinary rock unless sensitive methods are used. Cassiterite
