Abstract:For a polymetallic ore grading 47.79% Fe, 0.066% Cu and 2.05% S, a flowsheet consisting sequentially of low intensity magnetic separation (LIMS) for roughing, regrinding, flotation for desulfurization and LIMS for cleaning was adopted to recover iron, followed by another process consisting of Cu/S bulk flotation, desliming-dereagent, regrinding and Cu/S separation for copper and sulfur concentration. With the grinding fineness of -0.075 mm 50% for the first stage of grinding and regrinding of iron and Cu-S rough concentrates at the size of -0.075 mm 80%, an iron concentrate grading 66.63% Fe, 0.0072% Cu and 0.069% S with a recovery of 92.41% Fe, a copper concentrate grade of 20.25% Cu, 26.84% Fe and 27.80% S with a recovery of 52.16% Cu, as well as a sulfur concentrate grading 44.00% S, 43.04% Fe and 0.15% Cu with a S recovery of 78.72% were prepared. Therewith, iron, copper and sulfur resources in this Fe-polymetallic ore can be recovered comprehensively.
Keywords:Fe-polymetallic ore  Fe-Cu-S resources  flotation  magnetic separation  regrinding of rough concentrates
