摘 要: | 黑龙江某片麻岩鳞片石墨矿石结构属于片麻岩型石墨矿,脉石矿物以石英、长石、白云母为主,金属矿物有少量的褐铁矿。原矿总固定碳含量为8.03%,通过酸浸-碱熔-酸洗分析得知:原矿中+0.15 mm大鳞片石墨的固定碳含量占总固定碳含量的37.58%。原矿经一次粗选一次扫选、粗精矿八次再磨八次精选的阶段磨浮工艺流程,最终获得的精矿固定碳品位90.53%、精矿固定碳回收率94.07%。其中+0.15 mm精矿固定碳品位达到95.26%、固定碳回收率为17.67%,+0.15 mm大鳞片石墨的保护率为47.02%。

Abstract: | The structure of a certain graphite ore in Heilongjiang province belongs to gneiss type graphite ore, the gangue minerals are mainly quartz, feldspar and mica, and the metal minerals contain a small amount of limonite. The total fixed carbon content of the raw ore is 8.03%. The fixed carbon content of + 100 mesh large scale graphite in the raw ore accounts for 37.58% of the total fixed carbon content. After the process of one roughing, one scavenging and eight regrinding and eight cleaning, the fixed carbon grade of concentrate is 90.53% and the fixed carbon recovery rate of concentrate is 94.07%. Among them, the fixed carbon grade of + 0.15 mm concentrate is 95.26%, the fixed carbon recovery rate is 17.67%, and the protection rate of +0.15 mm large scale graphite is 47.02%. |
