| Abstract: | According to the mineral processing results of iron pyrite of Yunfu Guangye Group,some technological measures were investigated to increase the recovery of pyrite in concentrates and reduce the grade of pyrite in tailings.The flow sheets of"selective flotation for removing carbon","regrinding and reprocessing of the middlings from cleaning Ⅱ"and"regrinding of the tailings"were tested,finally,the scheme of"regrinding and reprocessing of the middlings"was proposed as a feasible technology. |
