都龙矿区螺旋溜槽尾矿中锡石回收工艺试验研究
发布时间:2018-11-15 09:22
【摘要】:都龙矿区新田选矿厂+37μm粗粒级锡石重选工艺中螺旋溜槽尾矿采用摇床重选的作业回收率仅35%左右,难以达到高效回收细粒级锡石的目的。鉴于细粒锡石浮选工艺技术在生产中已获得成功应用,采用浮选工艺回收螺旋溜槽尾矿中锡石可以获得锡粗精矿含锡品位8.03%、作业回收率89.23%的试验指标,相对摇床重选工艺能大幅度提高锡石的回收率。同时将浮锡尾矿尾水回用,在获得相近指标的条件下,可降低药剂耗用量10%~20%,有利于降低药剂成本。
[Abstract]:In the 37 渭 m coarse grained cassiterite gravimetric separation process in Dulong mining area, the recovery rate of spiral chute tailings is only about 35%, so it is difficult to recover fine cassiterite with high efficiency. In view of the successful application of fine cassiterite flotation technology in production, the cassiterite from spiral chute tailings can be recovered by flotation process, and the tin-bearing grade of coarse tin concentrate is 8.03 and the operational recovery is 89.23%. The recovery rate of cassiterite can be greatly improved by the gravity separation process of rocker. At the same time, reusing the tailings of the floating tin tailing can reduce the consumption of 10% and 20% of the reagents under the condition of obtaining similar indexes, which is beneficial to reduce the cost of the reagents.
