Gangue refers to the waste material that accompanies valuable minerals in ore deposits, primarily in mining contexts. In the context of 'ground gangue,' it is likely referring to gangue that has been extracted and is located on the surface, such as in a gangue hill. The term 'gangue slurry' indicates that the gangue has been mixed with water and possibly other additives to create a slurry for backfilling in mining operations. This slurry can be used to fill voids in mines, such as goafs, which are the collapsed areas left after coal extraction. The process involves crushing the gangue, mixing it with water and additives, and pumping it to the desired location.
