攀枝花钛铁矿在回转窑中800℃下轻度氧化予理处后,进行流态化三段逆流稀盐酸常压浸出,能有效地防止钛铁矿在酸浸过程中的粉化,生产出与原矿粒度相仿的高品位富钛物料。经年产金红石60吨规模的扩大试验,进一步验证了这条工艺流程的效能,自行设计的流态化塔和双塔双槽配置,设备简单,结构合理,操作方便,设备材质易解决,很好地实现了这一工艺过程。试验获得的产品品位平均91.37％,过程粉化率0.49％,每吨金红石的成本为1104.3元。
Panzhihua ilmenite in the rotary kiln at 800 ℃ under the mild oxidation to the Department, the fluidization of three countercurrent dilute hydrochloric acid leaching, can effectively prevent ilmenite in the acid leaching process to produce High grade titanium-rich material with similar particle size. The annual production capacity of 60 tons of rutile scale test, to further verify the effectiveness of this process, the design of the fluidized tower and twin towers double slot configuration, simple equipment, reasonable structure, easy operation, easy to solve the material equipment, it is very easy Good to achieve this process. The grade of the product obtained by the test was 91.37% on average, the rate of the process was 0.49% and the cost per ton of rutile was 1104.3 yuan.
