Working principle:
the flotation column adopts a machine column continuous flotation column, can realize combined cascade intensified flotation, and aims at the defects of a flotation machine and a flotation column, a countercurrent mineralization area is arranged at the lower part of an impact stirring type flotation machine, so that a mineral discharge port of the flotation machine is far away from a strong turbulence area, the problems of ore pulp short circuit and trough phenomenon of the traditional flotation machine and low mineralization intensity of the flotation column are overcome, cascade intensified flotation is realized, and on the basis of supporting an ultra-fine particle flotation process flow, the ultra-fine particle rare earth mineral recovery application problem is solved by matching with a high-efficiency rare earth collector, and the ultra-fine particle rare earth mineral is effectively recovered and qualified rare earth concentrate products are directly produced by only using a single flotation means.
The thickener is 500m 2 Inclined plate thickener, considering that the initial concentration of the selected material is about 5-10% lower, the pulp flow and fluctuation range are larger, and 500m is utilized 2 The inclined plate thickener and the concentration cyclone form a two-stage classification loop to realize concentration classification of ultrafine rare earth materials with low concentration (5-10%), thereby playing roles in buffering pulp flow fluctuation and pre-concentration, the large-volume storage bin of the inclined plate thickener plays roles in buffering pulp, and the expansion application effect of the inclined plate reaches 500m 2 By applying the shallow layer sedimentation principle, the sedimentation time of fine-grained materials is shortened, the production continuity requirement of downstream recovery operation is met, the rapid sedimentation and concentration of the materials are realized, and the sedimentation time is 500m 2 The inclined plate concentrator can raise the concentration of material from 5-10% to 10-15%, and the specific concentration process is that the mixed ore pulp (concentration 5-10%) formed by overflow in the externally poured low-two-tail and large-intensity magnetic tailings and concentrating cyclone directly enters 500m 2 The inclined plate thickener is concentrated rapidly in one stage, overflow of the thickener is discharged to enter a water return tank for return water, tailings of an underflow outlet (concentration 10-15%) mixed fine-sweeping flotation column of the thickener are pumped into a concentration cyclone by a first slurry pump, and overflow of the concentration cyclone returns to 500m 2 The inclined plate thickener is formed into a concentrating closed circuit, the sand setting concentration of the concentrating cyclone reaches 30-35%, and the concentration requirement of the subsequent ultra-fine particle grade rare earth flotation technology on the selected materials is met.
500m 2 Inclined plate thickenerThe application of (2) provides a proper graded concentration stable flow and feed concentration for the concentrate cyclone, the concentrate cyclone separation particle size and graded concentration are mainly dependent on the concentrate cyclone diameter and feed concentration, the smaller the diameter, the smaller the separation particle size. The phi 100 or phi 75 cyclone is selected, the concentration requirement can be met under the condition of proper ore feeding pressure and feeding concentration, and the ultra-fine rare earth flotation process has good recovery effect on the fine ore with the granularity below 800 meshes, so that the property requirement on the feeding material is full-size flotation recovery, namely, the prior desliming is not needed, the 325 meshes of the feeding material account for 80 percent, and the process property has no clear requirement on the separation granularity of the concentration cyclone, so that the concentration cyclone only plays a role in concentration, has no strict requirement on the granularity separation effect, and the overflow closed loop of the concentration cyclone returns 500m 2 The inclined plate thickener overflows normally to clear backwater and returns to other processes.
The concentration of the settled sand through the concentration cyclone reaches 30-35%, the main purpose of the ball mill is to break the flocculation and the package state of the micro-particle materials, so that the micro-particle materials and the acting surface of the medicament are displayed, the flotation recovery of the downstream flotation process is facilitated, and the economic control and the on-site production condition are considered.
