Tin & Tungsten Mines in Burma with Nick Gardiner

Collectively, these belts have been the dominant global historical producer of tin, which was overwhelmingly sourced from fairly destructive dredging of alluvial deposits in Malaysia and Thailand. However, in Burma there are many primary deposits – including the Mawchi Mine, which pre WW2 was the world's largest tungsten producer.

List of Countries By Tungsten Production - WorldAtlas

Tungsten is known for its extremely high melting point which at temperatures of 3,400 degrees Celsius, is the highest of any metal. The metal boils at temperatures exceeding 5,930 degrees Celsius, the second highest boiling point of any metal on earth. Tungsten is produced from wolframite and scheelite ores.

Formation of tin ore deposits: A reassessment - ScienceDirect

Placer deposits, i.e. secondary tin deposits in surface sediments, are historically the starting point of tin mining, and still today provide nearly half of all tin production ().The only economically important tin mineral is cassiterite (SnO 2), which is a heavy mineral (7.15 g/cm 3) and mechanically and chemically resistant.Therefore, cassiterite becomes enriched in heavy-mineral ...
