Antimony Refining Technique

Interagency Agreement Between the Mine Safety and Health

Mar 29, 1979Mining has been defined as the science, technique, and business of mineral discovery and exploitation. It entrails such work as directed to the severence of minerals from the natural deposits by methods of underground excavations, opencast work, quarrying, hydraulicking and alluvial dredging.
