680m^3超大型浮选机工业试验的流程考查分析

Examination and Analysis of the Flotation Flowsheet in Industry Test of 680m^3 Super-large Floatation Machine

在前期充分研究分析的基础上,某铜矿采用 680m^3 超大型浮选机对尾矿进行了强化再选的工业试验研究。试验流程考查结果表明,680m^3 浮选机设计合理,无明显短路死区现象,浮选时间达到了设计预期要求,浮选时间达 17.97min;生产流程稳定,指标波动小,铜浮选回收率达 88.24%;680m^3 浮选机对粗粒级矿物回收效果显著,矿物富集比高达 9.17 倍,达到了试验的预期目标。

On the basis of full research and analysis in the earlier stage, the industrial test of enhanced coarse-fraction separation of tailings in a copper mine was carried out by using 680m 3 super-large floatation machines. The flowsheet examination test results show that 680m 3 flotation machine has reasonable design, no obvious short-circuit dead zone phenomenon, flotation time meets the design expectation, flotation time reaches 17.97 minutes;production process is stable, index fluctuation is small, copper flotation recovery rate reaches 88.24%;680m 3 flotation machine has remarkable effect on recovery of coarse-fraction minerals, and the enrichment ratio reached 9.17 times. The test results reached the expected target.
