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.
