【摘要】 以磁选分离辽宁凤城硼镁铁矿石中磁铁矿后的矿石为原料,开展重选法回收其中铀矿物的研究。结果表明,经水力旋流器、螺旋溜槽和摇床联合分选,可以自含铀0.006 3%的原料中分选出品位为0.216%的铀精矿,铀回收率为44.24%。该分选方案具有较好的可行性。进一步提高铀矿物单体解离度是改善分选效果的重要途径。更多还原

【Abstract】 A laboratory research was carried out to recover uranium mineral from Liaoning Fengcheng ludwigite ore.Gravity concentration methods including hydroclone,spiral chute and shaking table were applied in this study.The results show that a concentrate with uranium grade of 0.216% and recovery of 44.24% could be produced from the feed of uranium content 0.006 3%.This research is helpful to comprehensive utilization of the mineral resources.Increasing further uranium mineral liberation degree is the key to improve separation effects.更多还原
