Cassiterite
Cassiterite heavy metallic hard tin dioxide (SnO2) that is the major ore of tin It is colourless when pure but brown or black when iron impurities are present Commercially important quantities occur in placer deposits but cassiterite also occurs in granite and pegmatites Early in the 15thThe tin ores of Bolivia are in part of high grade and yield a production of great importance Many of the Bolivian vein-deposits are very rich they commonly carry an average of 20 per cent or more of tin oxide and some of the veins consist of almost solid cassiterite

Cassiterite Facts
Interesting Cassiterite Facts Casiterite may precipitate from volcanic gas The name cassiterite comes from the Greek term kassiteros meaning tin The prominent features of cassiterite is its high specific gravity high hardness and streak color Another variety of cassiterite includes needle tin which is an acicular form of cassiterite The main recently available resources of thorium are coupled with monazite-enriched placer deposits in alluvial or marine sediments occurring mainly in Australia India Brazil Venezuela the USA and Egypt These deposits contain variable proportions of monazite ilmenite rutile xenotime zircon and/or cassiterite

Pyrometallurgical Extraction of Tin Metal from the
Abstract — This study aims to investigate the Pyrometallurgical extraction of tin metal from the Egyptian cassiterite concentrate The carbothermic reduction of cassiterite concentrate by char coal in the Na R 2 R CO R 3 R - NaNO R 3 R molten salt system was studied at the temperature range 850 The smelted tin can then be added to smelted copper to produce bronze Alternatively copper ores and cassiterite ores could have been mixed before smelting and smelted together This method might have produced alloys with variable tin percentages although cassiterite is a high density ore containing almost 80% tin in most cases

Cassiterite Flotation
The nominal size range for cassiterite flotation is between 2 and 100 microns The top size is variable depending upon the liberation of the cassiterite particles Cassiterite grains coarser than 100 microns are difficult to float whilst grains finer than 2 microns give selectivity problems Hence the feed for cassiterite flotation should be reduced to 95% minus 100 microns and then deslimed
