Product Description
Coal Gangue
Introduction:
Coal gangue is the solid waste discharged in the process of coal mining and coal washing. It is a kind of black gray rock with lower carbon content and harder than coal that is associated with coal seam in the process of coal formation.It includes the gangue excavated in the process of roadway excavation, the gangue extracted from the roof, floor and interlayer in the process of excavation, and the washing gangue picked out in the process of coal washing.Its main components are Al2O3, SiO2, in addition to different amounts of Fe2O3, CaO, MgO, Na2O, K2O, P2O5, SO3 and trace rare elements (gallium, vanadium, titanium, cobalt).

1. Recovery of coal and pyrite: through simple process, good coal is washed from coal gangue, inferior coal is selected through screening, and pyrite is picked out at the same time.Or from the coal preparation of the jig - plane shaker process recovery of pyrite, wash coal and coal blending.Recycled coal can be used as fuel for power boilers, washed gangue as building materials and pyrite as chemical feedstock.
2. Used for power generation: mainly used for mixed burning of coal washing and gangue washing for power generation.China already generates electricity by burning a mixture of washing coal and gangue (calorific value is about 2,000 kcal/kg) in a fluidized furnace.Slag can produce slag brick and slag cement.
3, manufacturing building materials: instead of clay as a brick raw material, you can dig less good fields.When making bricks, using the combustible material of coal gangue itself can save coal.
4. Coal gangue can also be used for the production of low calorific value gas, the manufacture of ceramics, the production of soil amendments, or used for paving, underground filling and ground filling.In the gangue hill after spontaneous combustion can also be planted grass afforestation, beautify the environment.
