| titleOfInvention | Beneficiation method for ultralow-grade iron ore |
| abstract | The invention provides a beneficiation method for ultralow-grade iron ore. The beneficiation method comprises the following steps that dry separation ore is obtained after raw ore is subjected to three-stage crushing, two-stage dry separation and screening; the dry separation ore is subjected to two-stage closed circuit ore grinding, two-stage magnetic separation and concentration magnetic separation, and iron ore concentrate and tailings pulp are obtained; and the tailings pulp is subjected to one-stage closed circuit dehydration, tailings sand is obtained and mixed with blast furnace water quenching slag, crushed stone and cement, and then bricks are made. In the beneficiation method provided by the invention, before beneficiation, surrounding rock, waste rock and the like mixed in the raw ore are thrown away through three-stage crushing, two-stage dry separation and screening treatment to achieve more crushing and less grinding, the treatment quantity of ore grinding is decreased, and the ore grinding cost is lowered. In addition, the tailings sand is mixed with the blast furnace water quenching slag, the crushed stone and the cement, and then the bricks are made, so that recycle of tailings is achieved. |
