Asbestos in Mines Asbestos is a naturally-occurring mineral mined for and used since ancient times. Its earliest uses were as a strengthener for earthenware pots and other cooking tools. However, as its use became more widespread, these ancient peoples quickly learned of its risks associated with it.
Significant waste volumes are associated with copper production. Mine wastes may contain radionuclides due to their natural presence in ores and can be a source of TENORM. Uranium, which may be co-located with copper ore, may also be recovered as a side stream, if economical. ... Asbestos, Overburden from Uranium Mining, ...
Despite proof that the dust associated with asbestos mining and milling causes asbestos-related disease, mining began at Wittenoom in 1943 and continued until 1966. In 1974, the first public warnings of the dangers of blue asbestos were published in a cover story called "Is this Killer in Your Home?" in Australia's Bulletin magazine.
