Mining in Cornwall and Devon, in the southwest of England, began in the early Bronze Age, around 2150 BC, and ended (at least temporarily) with the closure of South Crofty tin mine in Cornwall in 1998. Tin, and later copper, were the most commonly extracted metals.Some tin mining continued long after the mining of other metals had become unprofitable.
However, by far the greatest extension in the use of copper resulted from Michael Faraday's discovery of electromagnetic induction in 1831 and the way that the effect could be used to generate electricity. The same principle was used to develop electric motors. The electric lamp was invented by Sir Joseph Swan in 1860 and brought to a commercial design by Thomas Edison in 1879.
It wasn't until the 18th Century and the invention of machine driven pumps, that Cornish tin mining became a truly capitalist concern. Mine shafts inevitably dropped below water level, so prior to this date, shallow mining was the only way to extract the tin and copper from the ground.
