Asbestos: Geology, Mineralogy, Mining, and Uses

Most 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 used. In the production, or industrial applications, of asbestos fibers, several parameters are
