  • How asbestos is made material, history, used, </h3>THE MANUFACTURING PROCESSAsbestos is a general name that applies to several types of fibrous silicate minerals. Historically, asbestos is best known for its resistance to flame and its ability to be woven into cloth. Because of these properties, it was used to make fireproof stage curtains for theaters, as well as heatresistant clothing for metal workers and firefighters.

Quebec was a large mining area, though mines operated in cities throughout Canada. At one point, Canada had several dozen mines in operation and was the largest exporter of asbestos to the U.S. and many other countries.

  • Asbestos Mining, Processing Methods, amp; Production </h3>DESCRIPTION OF ASBESTOS ORE ROCK PROCESSING BY MACHINEHand cobbing is the oldest 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. See Figure 1.4 at leftSeveral processes or

    20021021ensp;0183;ensp;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.
