specific Embodiment approach 1
[0015] Specific implementation mode one: the method for comprehensive recovery of valuable minerals from river tailings in this embodiment is carried out according to the following steps:
[0016] 1. The river tailings are pre-selected and thrown by a sawtooth wave jig and / or spiral classifier to obtain river tailings with a particle size d≤2mm, and then ball milled by a ball mill to obtain ore pulp;
[0017] 2. Pass the ore pulp obtained in step 1 through a magnetic separator to obtain iron concentrate and first-grade tailings after magnetic separation;
[0018] 3. The primary tailings are selected by shaking table to obtain the secondary concentrate and secondary tailings;
[0019] 4. Secondary concentrate flotation of arsenic-iron-sulfur ore to obtain arsenic-iron-sulfur ore and third-grade tailings;
[0020] 5. Three-stage tailings flotation lead-zinc concentrate to obtain lead-zinc concentrate and four-stage tailings;
[0021] Sixth, the fourth-grade tailings flotation ...
specific Embodiment approach 2
[0023] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that during the pre-selection of tailings in step 1, the river tailings with a particle size of d are pre-selected and discarded, and the river tailings of 0.45mm≤d≤2mm use sawtooth The wave jig pre-selects the tailings; for the river tailings with a particle size d<0.45mm, the spiral classifier pre-selects the tailings. Others are the same as in the first embodiment.
specific Embodiment approach 3
[0024] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is that the particle size d≤0.165mm of the river tailings in the pulp in step one, and the mass percentage of the river tailings in the pulp is 95% to 98%; other It is the same as the specific embodiment 1 or 2.
