Wolframite contains iron, manganese and tungsten and is the main ore mineral of tungsten. Until the mid 1800s it was treated as a waste product but it later became a high value by product at many tin mines in Cornwall. The Castle an Dinas tungsten mine, in the St Austell Mining District, operated on a limited scale during the First World War and Second World War and production peaked between 1945-1958 when around 3,000 tons of wolframite was produced
