question

are there any tin mines left in cornwall
passage · full text (780 characters)
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.
