Embodiment 1
[0026] The specific flow process of the sorting method of the Anshan type lean iron ore of the present embodiment is as follows figure 1 shown, and follow these steps:
[0027] (1) Send the raw ore of Qidashan Iron Mine into a closed-circuit grinding system to obtain raw ore powder with a particle size of -0.074mm accounting for 58.17% of the total weight;
[0028] (2) Send the raw ore powder into the hydrocyclone for coarse and fine classification, the grading particle size is 36 μm, the overflow yield rate of the hydrocyclone is 41.63%, and the underflow is fed into the spiral concentrator for rough separation, and the rough separation is obtained Concentrated ore, rough ore and rough beneficiation tailings, the rough beneficiation concentrate is sent to the spiral concentrator and then be beneficiated, and the beneficiation will be the beneficiation concentrate, the beneficiation middle ore and the beneficiation tailings, the concentrate Concentrated ore is gravity-concent...
Embodiment 2
[0033] The specific flow process of the sorting method of the Anshan type lean iron ore of the present embodiment is as follows figure 1 shown, and follow these steps:
[0034] (1) Send the raw ore of Qidashan Iron Mine into a closed-circuit grinding system to obtain raw ore powder with a particle size of -0.074mm accounting for 58.17% of the total weight;
[0035] (2) Send the raw ore powder into the hydrocyclone for coarse and fine classification, the grading particle size is 25 μm, the overflow yield rate of the hydrocyclone is 33.61%, and the underflow is fed into the spiral concentrator for rough separation, and the coarse separation is obtained Concentrated ore, rough ore and rough beneficiation tailings, the rough beneficiation concentrate is sent to the spiral concentrator and then be beneficiated, and the beneficiation will be the beneficiation concentrate, the beneficiation middle ore and the beneficiation tailings, the concentrate Concentrated ore is gravity-concen...
Embodiment 3
[0040] The specific flow process of the sorting method of the Anshan type lean iron ore of the present embodiment is as follows figure 1 shown, and follow these steps:
[0041] (1) Send the raw ore of Qidashan Iron Mine into a closed-circuit grinding system to obtain raw ore powder with a particle size of -0.074mm accounting for 59.2% of the total weight;
[0042] (2) Send the raw ore powder into the hydrocyclone for coarse and fine classification, the grading particle size is 20 μm, the overflow yield rate of the hydrocyclone is 21.72%, and the underflow is fed into the spiral concentrator for rough separation, and the coarse separation is obtained Concentrated ore, rough ore and rough beneficiation tailings, the rough beneficiation concentrate is sent to the spiral concentrator and then be beneficiated, and the beneficiation will be the beneficiation concentrate, the beneficiation middle ore and the beneficiation tailings, the concentrate Concentrated ore is gravity-concent...
