The TFe grade of a foreign iron ore is 49.04%. It is mainly dominated by hematite with a distribution rate of 91.49%, which is patchily and granularly embedded. In this paper, the beneficiation test was carried out by the "stage grinding-stage strong magnetic" process. The iron ore concentrate with 65.26% TFe grade and 74.40% total recovery was obtained under the conditions: 55% of particles less than 0.076 mm in the first stage grinding, 857 kA/m in the strong magnetic roughing field, 65% of particles less than 0.076 mm in the second stage grinding, the strong magnetic selection field strength was 239 kA/m, the strong magnetic sweeping field strength was 477 kA/m. In order to achieve comprehensive utilization of tailing resources, sand fishing test was conducted and obtained 41.47% TFe grade of coarse sand, which can be returned to grinding operation; 13.10% TFe grade of fine sand, which can be used as construction material; 35.55% TFe grade of fine tailing, which can be re-elected for tailing or used as iron correction material for cement.
