A Review on Coagulation/Flocculation in Dewatering of Coal Slurry

Coal slurry is an essential component of mining operations, accounting for more than half operating costs. Dewatering technology simultaneously confronted with obstacles and possibilities, it may yet be improved as the crucial step reducing ultimate processing cost. Coagulation/flocculation used a dewatering process that reasonably cost-effective user-friendly. This paper reviews application different coagulants/flocculants their combinations in mechanisms. In this context, various polymeric flocculants are discussed coal depth. Many operational parameters influence performance flocculation also presented. Furthermore, discussion provided on mechanism flocculants’ interaction, strategy combining flocculants, efficient selection methods flocculants. Finally, coagulation/flocculation remaining challenges technological improvements better development highly treatment were highlighted, focusing intricate composition its difficulties.
