| Abstract: | Beneficiation technique of Jingtieshan-type iron ore was optimized based on the current technique adopted in JISCO. The metal recovery can be greatly increased by using a flowsheet of classification-roasting-magnetic separation-reverse flotation for lump ore and classification-high intensity magnetic separation for fine ore. The filtration puzzle of fine iron concentrate can be solved with a plate-type pressure filter, which can be referenced as a new approach for filtration of fine iron concentrate of the same type. |
