Asbestos ore & mine locations: Where has asbestos been mined around the world, where are the principal asbestos deposits? This article describes the locations of asbestos ore deposits around the world and where asbestos was mined.
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.
Asbestos is made available to industry either directly from
the mines or through distributors. Ninety per cent of the
asbestos is obtained directly from the mines. Most of the
companies that mine asbestos use it principally as an ingredient
in their products and have only a secondary interest
in supplying it to other companies.

Asbestos ore deposits have been found in almost all quarters
of the world.
The chief producers of industrial asbestos
in the world are Canada, Russia, South Rhodesia and the
Union of South Africa. The Canadian asbestos deposits are
generally considered to be superior to others insofar as essential
properties of infusibility, tensile strength, fineness, low
iron content, and elasticity are concerned.
The United States is the world's largest consumer and
producer of asbestos products. The main source of asbestos
for United States is Canada providing approximately 90 per
cent of the asbestos used. Domestic asbestos contributes approximately
seven per cent.
United States Asbestos Ore Deposit Locations
Domestic deposits of asbestos are principally
found in the states of Vermont and Arizona with
small quantities available in North Carolina, Georgia, California,
Washington and Alaska.
In Vermont, chrysotile asbestos deposits are found in slipfiber
veins. Even though the slip fiber is quite long, it is
not suitable for textile production.
The United States with
its Vermont asbestos mines ranks next in order of importance
in the production of chrysotile to Canada and Africa.
These deposits supply approximately 3,000 tons of ore per
day to a modern plant producing close to forty thousand
tons of fiber per year, with a good proportion in the medium
length grades. See Figure 1.1 at left.
The Arizona asbestos is of the chrysotile variety and
occurs as cross fiber. Because of its extreme low iron content,
it is used primarily for electrical insulation and

Although amphibole asbestos is available in different localities
in the United States, the bulk of it is found in
Georgia. The output of amphibole asbestos in United States
is very small.
Asbestos MIne Locations in California Counties and the Eastern United States
The U.S.G.S. United States Department of Geological Survey reports (as of 2008) 542 locations in the U.S. where asbestos occurs naturally (and may have been mined). http://mrdata.usgs.gov/asbestos/

Excerpt Nevada and Utah asbestos deposits. Only a few, widely scattered asbestos deposits are
documented in Nevada and Utah. Most of these deposits are small occurrences of amphibole
asbestos, including one small past producer of mass-fiber tremolite asbestos in Utah
no. 1 mine. In the Southwestern U.S., tremolite and actinolite are commonly reported in the contactmetamorphic
(skarn) zone of metallic ore deposits, which formed where an igneous body intruded
and metamorphosed a magnesium-bearing carbonate rock. In most instances, the literature does not
describe the crystal form of the tremolite or actinolite. Thus, several instances of unreported fibrous
to asbestiform tremolite-actinolite may occur in skarn geologic environments in these States.
Also see ASBESTOS ORIGIN & NATURE which reports recent (2014-2015) concern with naturally-occurring asbestos deposits being disturbed (airborne asbestos) by the mining of asbestos-contaminated vermiculite, discussed by geologists in Boulder City, Nevada.

Canadian Asbestos Mines & Ore Locations
For the past 80 years [to 1959], the largest and most extensive
asbestos mining operations in the world have been
in the eastern townships of the Province of Quebec. Canada
produces asbestos in four provinces; i.e., Quebec, Ontario,
British Columbia and Newfoundland.
A predominant characteristic of Canadian asbestos, as
compared to asbestos in other countries, is the remarkable
degree of its uniformity as regards its chemical composition
and consequently in its technical properties. Modern
mill facilities are available. See Figure 1.2.

ventilated) mill in foreground, head frame of underground
mine at right, and open pit mine in background.

Since 1950 capital expenditures in the mining of Canadian
asbestos have been approximately $100,000,000.00. Approximately
95 per cent of the fibers mined is chrysotile. Some
production occurs in various locations in the mining of tremolite,
actinolite, and anthophyllite.
Asbestos Ore Deposits & Mining in Great Britain
The manufacture of asbestos products is a
major industry in Great Britain. The principal source of
asbestos is Africa. There are relatively no domestic deposits
in the British Isles.
Asbestos Ore Deposits & Mining in South Africa
The three important varieties of asbestos
are found in this area. Chrysotile is economically available
in large quantities. Crocidolite or Blue asbestos was discovered
in approximately 1803 in Cape Providence and
Transvaal in South Africa. "Amosite" was discovered in
1907 by a company known as Asbestos Mines of South
Africa. The name "Amosite" was derived from the initials
of the company.
Asbestos Ore Deposits & Mining in Southern Rhodesia
Chrysotile is the only variety of asbestos
found in Southern Rhodesia. This area ranks next to
Canada as a world source for chrysotile asbestos; although,
the Russian deposits are probably larger. There are different
mines in the area however, the largest and most popular
being the Shabani Mine.
Asbestos Ore Deposits & Mining in Russia
The enormous territory of the Union of Soviet
Socialist Republics contains asbestos deposits to such an
extent that it should be considered one of the principal producers
of asbestos in the world. However, these deposits are
generally considered second of importance to the Canadian.
Prior to World War I, Russia occupied second place among
the world's asbestos producers. Its largest asbestos mines are
situated in the Ural Mountains; deposits also exist in Siberia.
Russia is now [in 1959] reporting a production totaling 790,000
short tons, including 250,000 tons of Groups 7 and 8, with
plans for a very substantial increase which will bring the
annual figure to more than 1,000,000 tons. It is understood
that important chrysotile deposits are under development in
the Province of Kazakhstan in Middle Asia with the production
of 500,000 tons of fiber annually slated before 1960.
Asbestos Ore Deposits & Mining in Cyprus
The island of Cyprus is second to the Italian deposits;
it contains the oldest known asbestos mines. Greeks
obtained their asbestos for the eternal lamps and shrouds
of kings from these mines. Chrysotile is of prime importance;
however, most of the fibers are of the short variety.
Asbestos Ore Deposits & Mining in Italy
The asbestos industry originated in Italy through
the mines located in the North; the main area is around
Torino. Tremolite and chrysotile are of prime importance.
Asbestos Ore Deposits & Mining in Finland and Yugoslavia
World production of the amphibole
varieties of asbestos other than crocidolite and Amosite
comparatively limited. The larger quantity is apparently
mined in Finland and Yugoslavia. In 1956 Finnish production
was 18,000 tons. For the same year in Yugoslavia, production
was 8,000 tons.
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.
