【摘要】 就云南某地风化严重的细粒钛铁矿及伴生金红石进行了选矿试验研究,在采用弱磁选—强磁选工艺不能获得理想的指标后,采用弱磁选—强磁选—还原焙烧—弱磁选—浮选—重选—酸浸的工艺流程,获得了理想产品,铁精矿品位61.08%,回收率6.23%;钛铁精矿TiO2品位49.69%,回收率87.33%;金红石精矿TiO2品位86.57%,回收率11.77%。更多还原

【Abstract】 This article is due to carrying on separation research on serious weathering granule ilmenite and associated rutile ore in Yunnan,it cannot acquire the ideal separation index after the flowsheet of low intensity magnetic separation-high intensity magnetic separation,we adopt the low intensity magnetic separation-high intensity magnetic separation-deoxidizing roasting-low intensity magnetic separation-flotation-gravity separation-acid leaching flowsheet which acquires the ideal concentrate index: Iron concentrate iron grade of 61.08%,recovery of 6.23%;Ilmenite concentrate TiO2 grade of 49.69%,recovery of 87.33%.Rutile concentrate TiO2 grade of 86.57%,recovery of 11.77%.更多还原
