Chrysotile asbestos is usually found near the surface and can be accessed with an openpit mine. Other asbestos deposits are found at varying depths and may require tunnels as deep as 900 ft (300 m) to gain access. Asbestos fibers are formed by the gradual growth of mineral crystals in cracks, or veins, found in soft rock formations.

Description of HandCobbing Asbestos MiningDescription of Asbestos Ore Rock Processing by MachineMilling / Crushing Methods For Asbestos ProductionHand cobbing is the est method used in mining asbestos.This particular method is still used in order to obtainthe 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. This type of fiber is not processed through the standard crushing units during the milling operation of the shorter filers.
