Magnetic Separation Of Copper Tailing In Kazakhstan

magnetic separation-sulphuric acid leaching of cu–co–fe,the matte sample was crushed, wet ground and then magnetic separated to produce magnetically susceptible concentrate (mainly co–fe alloy). 95.75% of cobalt was recovered by magnetic separation and 87.8% of copper and 44.39% of iron remained in the tailings. the concentrate was leached further by sulphuric acid..recovery of pt and pd from pgm mine tailings by magnetic,coil magnetic separator with its strength varied from 120 to 240 mt was used to separate the tailings into magnetic, middling and non-magnetic fractions in a two-stage operation. up to around 2 wt% of the tailings was recovered as magnetic fraction in the final stage with pt.utilization of high-gradient magnetic separation–secondary,high-gradient magnetic-separation process. the flotation-tailings grade were separated by a high-gradient magnetic separator to obtain a magnetic concentrate yield of 22.03% (for raw ore). the copper grade was 2.06%, and the recovery rate was 31.10%. the yield of magnetic tailings was 76.32%, the copper grade was 0.64%, and the recovery rate was 32.8%..how fines dry magnetic separation could solve mining's,whatever its flaws, this technique is cheap and straightforward enough to ingratiate itself with mining engineers the world over. according to work by research and markets, the appetite for magnetic separation is expected to reach nearly $1bn by 2025, up from just $685m in 2019. even so, wet magnetic separation is far from perfect..
