Asbestos production volumes:
History of how much asbestos was mined and produced, through the 1950's gives an indication of the stunning growth in the volume of asbestos mined and used world-wide up to the early 1980's.
This articles series about the manufacture & use of asbestos-containing products includes detailed information on the production methods, asbestos content, and the identity and use of asbestos-containing materials.
The growth in volume of raw asbestos and manufactured
asbestos products continually increases. In 1957, Canada's
asbestos industry totaled more than 100 million dollars.

The 1957 industrial minerals report by the Mining Industry
of the Province of Quebec recorded annual shipments of
chrysotile asbestos according to grades. The report was
based on sales figures from Asbestos Corp., Ltd., Bell Asbestos
Mines Ltd., Canadian ,Johns-Manville Co., Ltd.,
Flintkote Mines, Ltd., Johnson's Asbestos Co., Nicolet Asbestos
Mines, Ltd., and Quebec Asbestos Corp., Ltd.
The Canadian exports in tonnage and dollar value according
to grades were: crude, 683 tons, valued at $567,731;
milled, 393,311 tons, valued at $73,948,689; shorts, 636,611
tons, valued at $32,541,989. The grand total of raw asbestos
was 1,030,605 tons, valued at $107,058,409. Total sales of
manufactured asbestos products for the year 1957 was
$1,880,097 with brake linings accounting for approximately
one-third of the sales.
Based on 1955 figures, the United States produced approximately
tons from various mines. Typical monthly
quantity of manufactured exports at the end of 1957 was
300 tons, valued at $34,590. The quantity for imports was
39,100 tons, valued at $3,950,000. For the same year of
1957, the United States Bureau of Census monthly quantity
of manufactured exports was 1,700 tons, valued at
$1,184,080. The quantity of imports was 2,400 tons, valued
Fortunately, for United States manufacturing plants, the
largest asbestos producing country in the world is a border
neighbor. Railroads run through the entire mining districts.
Asbestos is loaded on railroad cars, and it can be shipped
directly into the American continent without difficulty. From
spring to autumn, ocean shipments take place from Quebec
or Montreal. With the present St. Lawrence river project,
delivery of asbestos to the United States will probably result
in lower costs and faster shipments to certain areas.

Crude Asbestos #2 consists basically of crude 5/8-inch to 3/4-inch staple asbestos fibers
The United States War Production Board at the close of
World War II concluded that approximately 60 per cent of
the total asbestos used was in the manufacture of textile
goods. Non textile products amounted to 40 per cent. This
particular grouping did not include asbestos used in the
manufacture of such nonmilitary products as asbestoscement
products. The textile products included all friction
materials and other engineered products. The non textile
products were primarily those involving Navy insulating
In reviewing the use of asbestos in the United States for
products other than asbestos-cements, the United States
War Production Board determined that 63 per cent of the
asbestos used was employed in the fabrication of insulating
materials, 32 per cent was used for mechanical and electrical
applications and 5 per cent was for general usage.
Canada's asbestos ore reserves are estimated at 47 million
tons, based on a mine life of 50 to 75 years. This figure
includes a minimum of 20 years of open pit operations. It is
difficult to estimate total amount of asbestos fiber reserves,
inasmuch as mine owners consider the information to be
confidential. In addition, new asbestos ore deposits are being
discovered. These not only increase the present supply but
also the reserves.
Based on the afore-mentioned figure, and a recent United
States Department of Commerce review on this subject, the
conclusion is that there will continue to be an ample supply
of asbestos fibers. The basic problem will probably be how
to take advantage of available fibers.
The Western Hemisphere is self sufficient in chrysotile,
but research is definitely needed to develop substitutes and
the strategic and limited availability of amosite
and crocidolite. Chrysotile is the most important fiber;
fortunately, it is the most abundant.
