One of the most fascinating developments of Nature, it serves man through its unique combination of properties. Found in serpentine rock, Chrysotile Asbestos is a fibrous mineral which can be made into such products as textiles and papers, and, at the same time, maintain the qualities of an indestructible mineral. Many varieties of asbestos, found throughout the world, have commercial value. But of these, one-- Chrysotile Asbestos--is so superior that it accounts for a major portion of the world's industrial consumption, and Canada is one of the leading sources for Chrysotile Asbestos. Soft, white, silky, and yet as strong as steel, Chrysotile inorganic fibres serves mankind in many ways. Canadian Chrysotile Asbestos has increased the world's standard of living in traditional fire and heat resistant products and in numerous exciting new de velopments in this Age of Science. CAREY-CANADIAN MINES, LTD. Nowhere did Nature produce a finer Chrysotile Asbestos than in one small rectangle in the eastern section of Quebec. The deposits are located in the Serpentine Belt running northeasterly through the Eastern Townships of the Province. To this small rectangle, The Philip Carey Manufacturing Company came in 1918, acquiring an interest in two operating companies at East Broughton Station. In 1924, Carey took over complete control of the two properties and formed the Quebec Asbestos Corpora tion, Ltd., as a Canadian subsidiary. For thirty-four years Carey mined, milled and supplied high quality Chrysotile Asbestos from its Quebec Asbestos Corpora tion property. In 1948 it became apparent that ore reserves were be- coming exhausted and company geologists began a search for new deposits. A magnetic survey in 1949 in dicated the possibility of an exciting discovery, a large anomaly four miles northeast of East Broughton Station on the northeast end of the Pennington Serpentine Dike. After extensive title searches, options were obtained and, later, drilling and sampling were started. It soon became evident that not one but several large ore bodies had been discovered. The overburden of clay and gravel was removed from one of these ore bodies and a modern asbestos mill was erected on the property. The new mill went into operation on September 1, 1958, under the newly organized subsidiary, Carey-Canadian Mines, Limited. CAREY-CAN ADI AN MINING OPERATION Highest quality Carey-Canadian asbestos ore is mined by the efficient open pit method. A track-mounted, selfpropelled pneumatic drill bores 4" holes for blasting. After blasting, power shovels load the ore into diesel trucks which haul the ore a short distance to the mill. SGP 0019734 Carey-Canadian Milling Operation The large twelve-story asbestos mill was designed to process 2,000 tons of ore per 24 hours. Now, the mill can handle a much larger volume of ore per day. The mill is powered by electricity, and the heat dissipated by hundreds of motors is sufficient to keep the mil! building warm in the winter time. The ore is unloaded at the primary crushing building where it is reduced to a maximum of 4" pieces by a pri mary jaw crusher. The ore is then conveyed to the drying building for further crushing and drying. After the ore has been dried by louvre-type, oil-fired rotary dryers and reiuced to a maximum 1" size, it is stored in a large-cajjritv rock storage building. Quality control begins at Carev-Canadian's rock storage iuildtng--which is unique in the asbestos industry Asbestos ire differs in length of fibre from one section to another in he mine Ordinarily, the ore is milled just as it comes from he mine. Thus, the character of the ore going directlv from nine to mill dictates the milling operation. However, iarev-Canadian's new method of selective storage and elective feeding provides complete control of this problem. )re from different sections of the mine is stored m separate >r ns in the rock storage building. From a central con n. .nel in the mill, a particular tvpe of ore can be tlected and fed to the mill at a regulated rate Or two or tree varieties of ore can be blended and fed simultaneously Thus the right selection or mixture of ores can be fed to the mill for the desired grades of asbestos This modern system of uniform and selective mill feeding is a most im portant engineering advance for superior quality control. The ore is conveyed from the dry rock storage building to the main mill building where the fibre is released from the rock in vertical hammer mills, then picked up bv air from standard and gyrating screens and collected in cyclone collectors Huge fans at the top of the mill are capable of moving 800,000 cubic feet of air per minute. This air is used to pick up asbestos from screens and to lift asbestos from one operation to another. Thirteen tons of air are required for every ton of ore treated. Fibre collectors retain all but the fine fibres which pass on through to be gathered in the large fmes-collectionsvstem at the top of the mill Carev-C.anadian's Asbestos Floats are produced from the material collected bv this system. The released and collected fibres are cleaned and graded with standard graders and gyrating screens. Bulk densities are controlled with vertical fiberizers, and grit content is controlled with whizzers, or specific gravityseparators Maximum flexibility was designed into the circuits of this new mill to allow production of manv grades for various industrial requirements. Quality control was foremost in the minds of the designers of this mill; e.g . large-capacity fibre bin blenders were provided to assure uniforrrutv SGP 0019735 .

Push buttons control feed to mill 7 Gyrating screens for cleaning and grading fibre Quality Control To assure asbestos of the highest quality and uniformity, two laboratories operate continuously in Carey-Canadian's asbestos mill. The Production Control Laboratory runs quick tests at frequent intervals to check uniformity and grading. Samples are obtained by pushing buttons. The buttons actuate solenoid valves in the finished fibre flow lines, and the samples drop through piping into small bins installed in the wall of the laboratory. The Shipping Test Laboratory performs specific tests for individual customers to check the fibre before shipment. Samples are taken from every tenth bag throughout each lot and composited for testing. MILLED GRADES OF CANADIAN CHRYSOT1LE ASBESTOS Standard Canadian Chrysotile Asbestos Grades were set up by the Committee on Uniform Classification and Grading of Asbestos Mines Products, by authority of the Minister of Mines of the Province of Quebec. Classification of milled asbestos grades is based on the Quebec Standard Testing Machine. This machine separates and classifies into its component fibre lengths a one pound sample of asbestos fibre on Vi ", 4 and 10 mesh screens and pan by shaking action. The screens are shaken exactly 600 times at a speed of 328 R.P.M. The weight, in ounces of fibre, retained on each screen and in the pan determines the grade. For example, Grade 5R tests 0-0-10-6. V2 " mesh screen--0 oz, 4 mesh screen--0 oz. 10 mesh screen--10 oz. Pan--6 oz.

Shorts are used in liquids, semi-solids and solid com positions where strong flexible, inorganic fibres are needed to form interlocked reinforcing webs which add durability and toughness for resistance to heat, wear, breakage and abrasion. Carey-Canadian is a large producer of uniform grades of as bestos shorts. COMPOSITION OF CHRYSOTILE ASBESTOS Chrysotile asbestos is a hydrous magnesium silicate represented by the chemical formula 3Mg 0, 2Si 02, 2H2O. The fibre is finer than cotton, but, at the same time, the fibre is tough, flexible, infusible and resists time, fire, weather and many acids and alkalies. The fibre is as dense or heavy as the rock in which it occurs, yet these fibres when milled are light as thistledown. Chrysotile asbestos was formed millions of years ago when a combination of high pressures, hot liquids and gases acting at great depths dissolved the serpentine. Later the mass cooled and the liquified material recrystallized in the form of fibrous asbestos in cracks and seams in the serpentine. The percentage of fibre to rock in the ore is relatively low. Therefore, tremendous quan tities of ore must be treated to produce finished fibre. Physical Properties of Carey-Canadian Asbestos Fibres Carey-Canadian Chrysotile Asbestos is noted for very light color, uniformity of grading, relatively low iron content and freeness from rock particles and large fibre bundles. Other physical properties are: Specific gravity--2.2 to 2.3. Hardness--3.5 on Moh's scale, ph value--9.4. Research laboratories at the mine and in Cincinnati are ready to assist you with asbestos problems. Carev-Canadian Research Two complete research laboratories, one at East Broughton and one at Cincinnati, Ohio, constantly probe for better methods, to produce, test and use asbestos. Carey's extensive experience with asbestos and asbestos products is at your service to help solve problems relating to grade selection, blending and application of asbestos.

The com mercial value of the fibre in relation to its capacity for resisting heat is largely influenced by its chemical makeup, as also ate other de sirable properties. Its high magnesia content is mainly responsible for the fact that some fibres can be raised to high temperatures, some times JOOflPF. and higher, without visibly being effected. The commercial usefulness of Chrysotile Asbestos depends on its physical properties particularly in the length of the fibre. Chrysotile possess a characteristic green, translucent tinge on a silky lustrous and whitish background. It usually contains varying amounts of iron and aluminum silicates.
