摘要
某含炭低品位石煤钒矿,嵌布粒度细、共生关系复杂,选矿富集钒难度大,直接冶炼生产成本高。在矿石性质研究基础上,进行了选矿方案试验,经对比确定采用炭浮选-钒浮选的工艺流程对钒进行选矿富集,最终闭路试验获得的钒精矿产率为35.92%,抛尾率达到64.08%,钒总精矿V2O5品位为1.87%,总回收率为86.05%。成本估算结果 1 t原矿选矿成本为45.897元/t,仅为冶炼成本的15%左右,但可降低冶炼处理量64%以上,经济效益显著。
A low grade stone coal vanadium ore has characters of high grade carbon, fine disseminated extent, complex symbiotic relationship, which conduct to the difficulty of vanadium mineral processing. Based on the characteristics of stone coal in Hubei, process of carbon flotation ＋ vanadium flotation was adoped to enrich the grade of V205. The closed circuit test obtaioned a concentrate contains VEO5 1.87%, the recovery rate of vanadium concentrate is 86.05%. The cost of mineral processing is ￥45. 897 per ton,which is only about 15% of the smelting cost and the economic benefit is remarkable.
