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 grams per cubic centimetre, a low melting point of °C ( °F), and a high boiling point of 2,625 °C (4,757 °F). Tin is allotropic; that is, it takes on more than one form.

· Mining and processing. The DFS proposes the mining of the Mpama North pit using proven underground mining methods. The proposed processing plant, with a throughput capacity of 360 kilo tonnes per annum (ktpa), will use conventional gravity separation methods for the recovery of tin. The process starts with the crushing of the ore, with the coarse material accounting for 75% of the .
In this process copper ore is mined, crushed, ground, concentrated, smelted and refined. The mining, crushing and grinding portions of the processing are extremely energy intensive since the rock must be reduced essentially to talcum powder fineness in order to separate the copperbearing minerals from it.

Such smelting of copper and tin ores would render the process 'archaeologically almost undetectable' (Ottaway and Roberts 2009, 206), especially if little slag is produced or it is removed, potentially as part of the symbolism attached to the process. Likewise, melting/recasting could also have occurred in a small hearth using crucibles and a directed air .
