Mining and Quarrying have been major industries in Cornwall for centuries.
The best known mining industries have been tin and copper but other metals were also important. Cornwall was mined for lead, zinc, manganese, iron, silver, antimony, wolfram, arsenic and uranium. The last three working mines were Wheal Jane, Geevor and South Crofty with mining finally ending in 1998.
