Asbestos is a general term applied to certain fibrous minerals of two configurations: serpentine and amphibole. The only type of asbestos derived from serpentine minerals, chrysotile (also known as white asbestos), accounts for of the asbestos used in the world today (Natural Resources Canada 2006). Amphibole …
The asbestos mining industry in Canada shut down in 2012, leading to several decommissioned and some abandoned sites. In southeastern Quebec, asbestos mining residues cover an area of 2308 hectares. About 800 million tonnes of tailings are vestiges of this mining industry, along with socio-economic and environmental impacts …

Despite consistent health warnings, asbestos mining and manufacturing was an engine that could not be stopped. World production in 1910 exceeded 109,000 metric tons, more than three times the total in 1900. In the United States, increased consumption stemmed from the population's growing demand for cost-effective, mass …
Miners Strike. On 14 February 1949, about 5,000 workers walked off the job at four asbestos mines in Asbestos and Thetford Mines, Quebec.They rejected offers of arbitration because they felt labour arbitrators usually sided with companies. Among their demands were a $1 per hour wage, nine paid holidays, union participation in the …

The "striking, very disturbing" findings indicate that asbestos released from mining or manufacturing operations may pose health threats to entire communities, …
When W.R. Grace & Company took over operation of the mines in 1963, it knew the vermiculite was contaminated with asbestos and that it caused health complications. The company didn't warn anyone about the asbestos exposure, and mining continued until 1990.. An estimated 694 Libby residents have died of asbestos-related …
The asbestos industry at Wittenoom, Western Australia, emerged in the early 20th century when extensive deposits of asbestos were discovered in the region. The town of Wittenoom quickly grew around the asbestos mine, becoming one of the largest asbestos mining and milling operations in the world.
Many were not rehired, and little was done to alleviate the working conditions that would take many lives over the next generation. In 1974, Dr. Irving J. Selikoff, the world's foremost authority on asbestos-related diseases, described the asbestos mining towns of Quebec as the most dangerous in the world. (See also …
