After mining or quarrying, the asbestos fiber is freed by crushing the rock and is then separated from the surrounding material, usually by a blowing process. Only the longest of the fibers, at least 1 cm (0.4 inch), are suitable for spinning into yarn. Shorter fibers are used in such products as paper, millboard, and asbestos-cement building ...
