    material asbestos ore. The manufacture of asbestos products is primarily included by the Standard Industrial Classification (SIC) code 3292. This industry is comprised of establishments primarily engaged in the manufacture of asbestos textiles, asbestos building materials, except asbestos paper, insulating materials for covering boilers and pipes, and other products composed wholly or chiefly

    Production to 1956 is estimated at 590,000 tons of ore from which about 20,000 tons of asbestos were recovered. In 1947 the town of Wittenoom was built to service the nearby asbestos mine. It was built ten kilometres from the mine and mill as there was not a suitable area available to expand the original residential settlement. By 1951 the town had 150 houses and a population of over 500. In

    01/06/1997· The Coalinga ore, being highly sheared and pulverized, allows high yields of asbestos to be obtained by simple open-pit methods. In contrast, the Canadian ore has to be mined from pits by dynamiting and then crushed and milled to produce a commercial product. Processed Coalinga ore yields a much greater proportion of unit fibrils than the typical iong-fibred Canadian product, being uniformly

  • Miners and Asbestos Exposure | Tremolite Asbestos in

    Mining and milling activities to remove asbestos from underground rock exposes workers to dangerous levels of the carcinogen. Besides the workers, people who live near asbestos mines also have an increased risk of exposure. Tremolite Asbestos In Vermiculite Mines. Besides asbestos miners, generations of vermiculite and talc miners have been exposed to tremolite asbestos dust in mines.

  • How asbestos is made material, history, used, processing

    The ore contains only about 10% asbestos, which must be carefully separated from the rock to avoid fracturing the very thin fibers. The most common method of separation is called dry milling. In this method, the primary separation is done in a series of crushing and vacuum aspirating operations in which the asbestos fibers are literally sucked out of the ore. This is followed by a series of

  • 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. In the production, or industrial applications

    Outside the King City mill, a gated cluster of weathered buildings off Highway 101, a dune of raw asbestos ore, looking like a pile of dirty snow, long rose above the rooflines. The ore was mixed with water, and gravity machines separated tailings from slurry, which was pressed into cakes, dried and pulverized. The powder was airlifted into storage silos that fed bagging machines.
