Asbestos mineral extraction method – open pit mining
Archetypal asbestos mining in the United States used open pit extraction followed by the milling process. Max out manufacture of asbestos in the United States was way over the 299 million pounds/year capacity in the late 1960s and early 1970s.

Asbestos Mines - an overview ScienceDirect Topics
In 1896 the first asbestos brake linings were made by Ferodo Ltd in England. In 1907 brown (amphibole amosite, an acronym of ‘Asbestos Mines of South Africa’) asbestos was discovered in Transvaal (South Africa) and mined. Mining and production of blue (amphibole crocidolite) asbestos began near the town of Koegas (South Africa) in 1926.

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.
