【摘要】：萨尔哈布塔勒蓝晶石矿产于石榴蓝晶二云母石英片岩中,成分复杂,给有效分选带来难度。针对这个特点,创新性的采用"原矿-破碎-干磁抛尾-磨矿-螺旋溜槽抛尾-再磨-蓝晶石浮选-磁选除铁"工艺流程方案回收蓝晶石矿,试验结果为:蓝晶石精矿产率7.15%,Al_2O_3品位58.74%,Al_2O_3回收率20.97%,蓝晶石矿物量95.26%,矿物回收率75.53%;溜槽尾矿采用"筛分-重选-磁选"工艺流程回收白云母,干磁尾矿采用"重选-筛分-磁选"工艺流程回收石榴子石、白云母、黑云母。试验结果为:白云母精矿产率17.57%,矿物量98%;黑云母精矿产率9.48%,矿物量90%;石榴子石精矿产率3.36%,矿物量95%。试验表明该矿除蓝晶石矿物可利用外,伴生石榴子石、白云母、黑云母等矿物也可综合回收利用。最终产品蓝晶石精矿质量指标达到LJ-52国家标准要求。
[Abstract]:Salhabur Tall bluestone deposit in the garnet blue crystal dimica quartz schist, the composition is complex, brings difficulty to the effective separation. In view of this characteristic, the original ore-crushing-dry magnetic throwing tail-grinding-spiral chute tail-throwing-regrinding-blue crystal floatation-magnetic separation and removing iron "technological process was adopted to recover the blue quartz ore." The results are as follows: the yield of blue quartz concentrate is 7.15% and the grade of Al _ 2O _ 3 is 58.74%. The recovery rate of Al _ 2O _ 3 is 20.97, the mineral quantity of blue crystal is 95.26 and the recovery rate of mineral is 75.53.The chute tailings are recovered Muscovite by "sieving, gravity separation and magnetic separation" process. Dry magnetic tailings are used to recover garnet, Muscovite and biotite by gravity-sieve-magnetic separation. The results are as follows: the yield of Muscovite concentrate is 17.57 and the amount of mineral is 98; the yield of biotite concentrate is 9.48 and the mineral quantity is 900.The yield of pomegranate concentrate is 3.36 and the mineral quantity is 9550. The results show that the associated garnet, Muscovite, biotite and other minerals can also be comprehensively recovered and reused. The quality index of the final product is up to the LJ-52 national standard.
