The last U.S. asbestos extraction operation was the King City Asbestos Company mine in central California, which closed in 2002. Mining the toxic mineral is not allowed in the U.S. anymore. Asbestos mining is completely banned in Canada, South Africa and Brazil, among other countries. Russia currently dominates the global asbestos-mining industry.Exposure to airborne friable asbestos may result in a potential health risk because persons breathing the air may breathe in asbestos fibers. Continued exposure can increase the amount of fibers that remain in the lung. Fibers embedded in lung tissue over time may cause serious lung diseases including: asbestosis, lung cancer, or mesothelioma.

mesothelioma). Asbestos fibres have been found in air samples from WA gold-mines, and all three patients had worked in these mines (for five to 17 years) and had no other significant known asbestos exposure. To our knowledge, this is the first report of asbestos-related disease in gold-mine workers. PMID: 10212648 [Indexed for MEDLINE]All mining has the potential to expose workers to asbestos. Asbestos may be found in small quantities in many areas of the earth; therefore, it may be disturbed and contaminate air even in mines designed to excavate other minerals. Taconite mining in Minnesota is an example of a non-asbestos mine that exposed workers to this dangerous mineral.
