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.

Asbestos: Industry Profile

2.1 PRODUCTION PROCESS The asbestos industry is organized in the following manner. First, asbestos ore is mined and then milled to achieve a homogeneous, graded input, which is shipped to primary industries. These primary industries then process and modify the raw asbestos fiber to produce an intermediate or finished product.

How asbestos is made

Process Asbestos deposits are found underground, and the ore is brought to the surface for processing using conventional mining practices. Chrysotile asbestos is usually found near the surface and can be accessed with an open-pit mine.

Asbestos mineral extraction method – open pit mining technique

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.

The History of Asbestos

The early 1870s also saw the founding of large asbestos industries in Scotland, Germany and England. Italy had been mining tremolite asbestos for decades. Australians began mining asbestos in Jones Creek, New South Wales, in the 1880s. By the early 1900s, anthophyllite asbestos was mined in Finland.

Asbestos Mining, Processing Methods, Production

Hand cobbing is the oldest method used in mining asbestos. This particular method is still used in order to obtain the long asbestos fibers (Crudes 1 and 2). The hand cobbing asbestos mining operation involves releasing fiber from the asbestos ore rock by means of manually (by hand) hammering away the rock from the ends of fibers.
