In mining, gangue is the commercially worthless material that surrounds, or is closely mixed with, a wanted mineral in an ore deposit. It is thus distinct from overburden, which is the waste rock or materials overlying an ore or mineral body that are displaced during mining without being processed. Minerals that were once thought of as coal gangue, and were dumped as tailings, may later find a commercial use. When this happens the old dumps are often reworked to extract the wanted mineral. For example, in copper mines in the 19th century the mineral arsenopyrite was dumped until arsenic became popular as an insecticide later in the century.
According to the research, after being grinded into fine and superfine powder by ultra fine grinding machine, coal gangue can be used as filler in cement and concrete, and construction material in brisk. Coal gangue’s recycling using not only solve pollution of solid waste and piling up, but also widen coal gangue’s application.
Ultra fine grinding machine has been widely applied to coal gangue made cement production line. The production line usually use Jaw crusher, impact crusher,coal gangue ultra fine grinding machine. It’s very important to choose machine. Customers shall choose according to the required finished size and capacity.
