UBC Mining Method Selection (see Appendix II - Mining Method References) is a modified version of the Nicholas approach for selection of mining method based on orebody characteristice (refer Nicholas 1981). Selection involves summation and ranking of numerical values associated with orebody characteristics that reflect the suitability of a particular method.
The flowsheet below Explains the Extraction of Tin Ore as shown by a study adapted to the concentration of a lode tin deposit.Cassiterite (SnO2) is very friable and special considerations to crushing and grinding of the ore are necessary to avoid an excessive production of fines. The Mineral Jig is an important feature of this flowsheet to recover the coarse free tin mineral as soon as liberated.

The tin mining industry on Dartmoor, Devon, England, is thought to have originated in pre-Roman times, and continued right through to the 20th century, when the last commercially worked mine (Golden Dagger Mine) closed in November 1930 (though it saw work during the Second World War). From the 12th century onwards tin mining was regulated by a stannary parliament which had its own laws.
