本文主要研究内容
作者袁腾（2019）在《司家营铁矿工艺优化研究》一文中研究指出：司家营铁矿当前生产情况与设计比出入较大,尤其矿石品位贫化较为严重,设计矿石品位30.44%,而实际只有26.5%左右,且磁铁矿石在整体矿石结构中比例增加,使用现有流程进行加工已不符合企业降本增效需求,针对当前工艺流程进行了优化研究,使之与新的技术经济指标适应。对矿石进行性质分析,发现其为含有较高含量硅酸铁,以石英为主要脉石矿物且嵌布均匀性较差的矿石,可磨性略强于赤铁矿。全粒级预选抛尾试验采用CCTS0503永磁筒式磁选机在4000Oe场强下进行,所得尾矿品位为8.69%,产率18.72%。三磁精矿以四种不同阳离子捕收剂进行实验室反浮选试验可得68%以上品位的精矿,金属回收率均不低于80%。在工业试验中,使用139.67g/t的S-1捕收剂可以获得精矿品位69.24%、尾矿品位21.94%的技术指标,回收率达到90%以上;使用160.82g/t的T-12可以获得品位69.24%回收率达95.88%的精矿,此时尾矿品位18.40%。使用275g/t阳离子捕收剂,用挂槽浮选机对品位53.98%的二磁精矿进行反浮选,可得68%以上品位精矿,但不足75%的金属回收率要求尾矿需要进行再磨再选。对品位54.50%的二磁精矿在实验室条件下使用磁浮选柱进行选别可得品位67.12%、产率77.99%的铁精矿,此时铁回收率96.05%。尾矿经再磨再选后品位为9.82%。在三磁精矿品位58.56%的情况下,经过选别可获得产率为83.98%,品位为66.75%,金属回收率为95.73%的精矿,最终尾矿品位11.98%。采用淘洗机进行三磁精矿提纯试验,在固定磁场1100Oe,循环磁场1050Oe,补偿磁场1050Oe,上升水量控制为1100L/h,可得品位68.40%,回收率95.65%的合格精矿。图27幅;表39个;参43篇。
