The techniques used for the extraction of tin from dartmoor followed a progression from streaming through open cast mining to underground mining today there are extensive archaeological remains of these three phases of the industry as well as of the several stages of processing that were necessary to convert the ore to tin metal
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 729 grams per cubic centimetre a low melting point of 23188 c 44938 f and a high boiling point of 2625 c 4757 f
Tin ore dressing flowextraction mines tin ore dressing flowextraction mines dressing the ore cornish mining world heritage site during the 18th century most of the ore dressing or processing was done by hand or buddles where water flow and gravity separated the heavy tin ore from the lighter waste gangue minerals
In a tin concentrator an appliance was needed to furnish a suitable product for fine jigging from a pulp of the following position in the jigging process particles of cassiterite as small as 01 mm can be recovered provided they are not present in excess that is if the material treated on the jigs contains sufficient coarser sands to keep the interstices between the grains open
Vein and disseminated tin deposits are mined by the same methods used in hardrock mining of other nonferrous ores such as zinc the ore is broken by drilling and blasting transported to a concentrator where it is crushed and ground and then concentrated by gravity methods

Cassiterite tin ore extracting plant alluvial tin extraction is similar to alluvial gold beneficiation and usually screening ore washing and gravity separation processing are involved ie gravity separation is the only rough separation method for alluvial tin and alluvial gold mine
By the disintegration of tinbearing rocks and veinstones the cassiterite passes into the beds of streams as rolled fragments and grains or even sand and is then known as stream tin or alluvial tin this detrital tinore was probably used as a source of the metal before the primitive miners had learnt to attack the solid tinbearing rocks
