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.Asbestos - Wikipedia,People have used asbestos for thousands of years to create flexible objects, such as napkins, that resist fire.

This particular method is still used in order to obtain the long asbestos fibers (Crudes 1 and 2). The hand cobbing asbestos mining operation involves releasing fiber from the asbestos ore rock by means of manually (by hand) hammering away the rock from the ends of fibers.
