The invention provides a multiple sorting magnetic micro-fluidic sorter, comprising: the device comprises a feeding device, a sorting device, an upper tailing collecting device, a lower tailing overflowing device and a lower water supply device; wherein, the feeding device is used for conveying ore pulp; the middle upper part of the sorting device is provided with the feeding device and is communicated with an ore pulp outlet of the feeding device, so that magnetic particles in the ore pulp are sorted out to form concentrate, and the concentrate is discharged; the upper tailing collecting device is sleeved outside the sorting device; the lower tailings overflow means is arranged inside the sorting device in a region below the feeding means. According to the invention, through multiple separation and tailing discharge, the separation of impurity particles in ore pulp is more thorough, the separation efficiency is higher, the impurity discharge efficiency is effectively improved, and the grade promotion amplitude of concentrate is improved. |
