The mining operations at the Victory mine of the Arizona Asbestos Association (a JohnsManville subsidiary after 1916) began in 1914 A small experimental mill, which had a capacity of approximately 5 tons of mill feed per 8 hours, was built Four grades of mill fiber were produced in addition to the Nos 1 and 2 crude gradesMost of the asbestos mining operations are of the open pit type, using bench drilling techniques The fiber extraction (milling) process must be chosen so as to optimize recovery of the fibers in the ore, while minimizing reduction of fiber length Dry milling operations are the most widely usedAsbestos: Geology, Mineralogy, Mining, and UsesDemand and Output for Asbestos Mining Asbestos mining operations persisted as a result of the enormous demand for the raw material US manufacturers imported the majority of their asbestos, but they still made use of domestic asbestos mines US asbestos mines hit peak production in 1973 That year, operations mined 136,000 tons of theAsbestos Mining and Exposure | Mesowatch
