Limonite beneficiation process mainly includes washing - screening - gravity separation, high intensity magnetic separation. After ore crushing and grinding, will under washing - screening classification, coarse ore adopts gravity separation to obtain concentrate, the middle grain size using roller type strong magnetic separator to obtain concentrate, fines and slimes adopts high gradient magnetic separator to obtain concentrate.
In order to increase metal recovery, middle mine of gravity separation could consider regrinding re-separation.
