It lies on the northward slope of the central elevation of the county, among numerous tin and copper mines. Mining, metal working, stone-quarrying and the making of chemicals are the main industries.

Camborne (Cambron, Camron) formed part of the large manor of Tehidy, held at Domesday by the earl of Mortain and subsequently by the Dunstanville and Basset families. In the early 18th century copper and tin began to be worked vigorously at Dolcoath : in 1788 ore worth £2,000,000 and in 1882 ore worth £5,500,000 was produced. It was the scene of the scientific labours of Richard Trevithick the engineer, and of William Bickford, the inventor of the safety-fuze.
