Abstract

This work investigates superabsorbent (SAB) polymer application to dewatering of fine pyrite (P) and chalcopyrite (CP) mineral slurries. The results showed that significant pulp water absorption, reflecting dramatic dewatering and hence, compact sediment consolidation (up to 80 wt%), may be achieved within 15 min of contact time. The rate of slurry water absorption increased with both decreasing SAB particle size and initial slurry solid loading. The SAB dewatering performance was higher for the CP than the P slurry. SAB regeneration and re-use investigations showed that multiple recycle and greater water recovery can be achieved with a given sample.
