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, of asbestos fibers, several parameters are considered

Asbestos mineral Britannica

After mining or quarrying, the asbestos fibre is freed by crushing the rock and is then separated from the surrounding material, usually by a blowing process. Only the longest of the fibres, at least 1 cm (0.4 inch), are suitable for spinning into yarn. Shorter fibres are used in such products as paper, millboard, and asbestos-cement building materials. Asbestos’ brittle, smooth-surfaced ...

Woodsreef Mine - NSW Resources and Geoscience

Open cut mining for asbestos first occurred at Woodsreef from 1919 to 1923. The Chrysotile Corporation of Australia carried out large scale mining at Woodsreef between 1970 and 1983. Approximately 500,000 tonnes (t) of chrysotile, or white asbestos was produced from 100 million tonnes (Mt) of mined material. The former mine extends over an area of approximately 400 hectares.
