| Abstract: | A combined process flowsheet including selective flocculation for desliming, high intensity magnetic separation(HIMS) for gauge discarding and cationic reverse flotation was adopted to recover low-grade highly-mudded fine hematite ore from Yongzhou in Hunan Province. Results indicate that a magnetite concentrate with iron grade and recovery of 55% and 85%, respectively, can be collected after a flocculation desliming with polyacrylamide(PAM) as flocculant and HIMS with magnetic field intensity of 960 kA/m. After a following reverse flotation with cationic collector GE-609A, the grade and recovery of iron concentrate can be improved to 59.8% and 94.2%, respectively. |
