Asbestos is obtainable by various underground mining methods, but the most common method is openpit mining. Only about 6 percent of the mined ore contains usable fibers. The fibers are separated from the ore by crushing, air suction, and vibrating screens, and in the process are sorted into different lengths, or grades.
