Title Marble Gangue Crushing Industry
Description Marble gangue is a kind of solid waste discharged from marble mining and marble washing. It is a kind of black-gray rock with lower carbon content and harder than marble. In real life, if the gangue has not been treated by crusher and other equipment, it will seriously damage the environment. From the point of view of marble mining process, China produces 100 million tons of marble annually and discharges about 14 million tons of gangue. From the point of view of marble washing and processing, 20 million tons of gangue will be discharged per 100 million tons of coking marble washed, and 15 million tons of gangue will be discharged per 100 million tons of power marble washed. From these data, we can see that the discharge of marble is huge. A large number of piled marble not only occupies land and affects the ecological environment, but also pollutes the surrounding soil and groundwater by leaching water of marble. Marble gangue contains certain combustibles, which occurs naturally under suitable conditions and pollutes the atmosphere by discharging harmful gases, affecting the health of residents in mining areas. Therefore, the treatment of marble is imperative.
