How Asbestos is Mined, Mining Process | Mesothelioma ...

Mining Process. The magnometer receives a signal from underground magnetite, a mineral that is commonly found near asbestos deposits. When miners pinpoint a good location, they begin drilling. They form an open pit mine, which consists of flat walking surfaces that spiral down as far as the miners mine.
