The Quebec Asbestos Industry Mining and Milling

PRACTICALLY all of Quebec's chrysotile asbestos production derives from twelve mining and milling operations located in the "Eastern Townships" area of the province. The annual output of these twelve operations exceeds one million tons of chrysotile asbestos, valued at over one hundred million dollars, and is shipped to manufacturers spread over all six continental areas of the world. A total of approximately twenty million ton of asbestos ore yearly, or about seventy-five thousand tons a day, is mined. Individually, the operations vary in size from about two thousand tons to thirty thousand tons per day. Removal of waste rock and overburden to develop these ore tonnages varies greatly from one mine to another, but would probably average out at about a one to one ratio.
