The UBC mining method selection algorithm is a modification to the Nicholas approach with a various weighting factors system, which places more emphasis on stoping methods, thus better representing typical Canadian mining design practices (Miller . et al. 1995). Due to the performed study by Tatiya (1998) a mining method was selected
Tin processing: Tin processing, preparation of the ore for use in various products. Tin (Sn) is a relatively soft and ductile metal with a silvery white colour. It has a density of 7.29 grams per cubic centimetre, a low melting point of 231.88 °C (449.38 °F), and a high boiling point of 2,625 °C (4,757 °F). Tin is
