Asbestos production quantities: how much asbestos was produced? This article describes the total quantity of asbestos that was mined and shipped world-wide, listing asbestos production by quantity and giving additional detail by asbestos type.
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 Quantities Produced World-Wide in the 1950's
The method of mining, milling, and processing asbestos
depends on the type of asbestos being handled as well as
such specific physical characteristics as soft versus harsh
fiber. Since chrysotile fiber accounts for approximately 95
per cent of all the asbestos used, this discussion will pertain
to Canadian chrysotile.

For a satisfactory mining operation,
the content of fiber in the rock should range from 3 to 12 per cent.
Such variables as availability of labor, transportation facilities, and size of the deposit determine whether
or not a low asbestos content mine will be a profitable
Separately at ASBESTOS MINING & PROCESSING we describe how asbestos ores were mined & prepared for use in fabrication procedures that used asbestos fibers or other asbestos material.
Table 1.3 below gives the total world production of all types of
asbestos by countries for the year 1956.

* This figure of asbestos production for Russia represents an unofficial and unverified estimate. It includes 275,000 tons of grades 7 and 8 of asbestos material.
Table 1.4 below gives similar statistics to Table 1.3 for the
amphibole fibers only.
