Wolframite contains iron, manganese and tungsten and is the main ore mineral of the metal tungsten. It is found at many localities within Cornwall, in veins alongside cassiterite and closely associated with granites. Until the mid-19th century, wolframite was treated just as another impurity mineral or waste product.
