Coal gangue is a typical industrial waste, which will bring environmental challenges and resource depletion when piled up in large quantities, heavy metal pollution prominent problem. In this study, Ca3(PO4)2 calcium superphosphate fertilizer (CSF) were utilized to passivate coal at different levels, its passivation mechanism was discussed. The results show that both CSF can effectively reduce moderate or high levels of slight clean level. effect slightly better than Ca3(PO4)2. Through characterization before after simulation with Visual MINTEQ PHREEQC software, it found provide PO32-, while releases HPO3 –, ionized generate more finally forms insoluble soluble phosphate metals. Leaching experiments the treated samples contain obviously stable components, leaching risk lower untreated gangue. summary, method proves effectiveness fixing metals provides an effective for harmless treatment
