Mica is primarily found in igneous and metamorphic rocks. It occurs in large crystals or in the form of thin layers known as "books." The major mica-producing countries include India, Russia, China, Brazil, and the United States. The extraction of mica involves mining and quarrying. Open-pit mining methods are commonly used to access the mica ...

Mica mining in the central part of Sri Lanka in Mailapitiya off Kady has been carried out during the British regime before 1948. Investigations carried out in the area around Kandy - Mailapitiya shows occurrence of economically minable Phlogopite mica mineralization. The vein thickness of the Phlogopite mica varies from 0.1 cm - 0.8m

'Mining' is defined as the extraction of valuable minerals from the earth and it is undertaken mainly by using two techniques, namely surface mining and underground mining. Surface mining is the most common type of mining (85% of all mining is surface mining), and is the only technique used for heavy mineral mining. Sri Lanka, despite …
