| Abstract: | The gangue is a solid waste in coal industry and has a negative effect on environment and ecological balance. This paper expounds the situation of the comprehensive utilization of the gangue in our country at present, introduces the technical route of extracting three kinds of the coagulant agents including the poly-aluminium chloride, poly-aluminium silicate and poly-aluminium sulphate from the gangue by using the acid leaching method, and makes deep analysis on the current market demand and application prospect of the gangue. |
