caption_attribution_description: Deutsch: Ruinen der Poldice Mine bei Gwennap in Cornwall. Die Poldice Mine war vom frühen 16. Jh. bis 1930 in Betrieb. English: Ruins of the Poldice Mine in Gwennap, Cornwall. The Poldice Mine was active from early 16th century until 1930.
context_page_description: Mining in Cornwall and Devon, in the southwest of England, began in the early Bronze Age, around 2150 BC, and ended 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.
  Historically, tin and copper as well as a few other metals have been mined in Cornwall and Devon. As of 2007 there are no active metalliferous mines remaining. However, tin deposits still exist in Cornwall, and there has been talk of reopening the South Crofty tin mine. In addition, work has begun on re-opening the Hemerdon tungsten and tin mine in south-west Devon. In view of the economic importance of mines and quarries, geological studies have been conducted; about forty distinct minerals have been identified from type localities in Cornwall. Quarrying of the igneous and metamorphic rocks has also been a significant industry. In the 20th century the extraction of kaolin was important economically.
context_section_description: 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.
  Historically, tin and copper as well as a few other metals (e.g. arsenic, silver, and zinc) have been mined in Cornwall and Devon. As of 2007 there are no active metalliferous mines remaining. However, tin deposits still exist in Cornwall, and there has been talk of reopening the South Crofty tin mine. In addition, work has begun on re-opening the Hemerdon tungsten and tin mine in south-west Devon. In view of the economic importance of mines and quarries, geological studies have been conducted; about forty distinct minerals have been identified from type localities in Cornwall (e.g. endellionite from St Endellion). Quarrying of the igneous and metamorphic rocks has also been a significant industry. In the 20th century the extraction of kaolin was important economically.
