Technical Field
[0001] The utility model relates to the technical field of collophanite production equipment, in particular to a collophanite tailings pre-selection closed-circuit process system. Background Art
[0002] In the field of collophanite production equipment technology, tailings reselection has always been an important link. The traditional closed-circuit process of tailings reselection mainly uses the self-priming of the suction flotation machine to complete the slurry feeding. In the flotation process, the foam tailings return to the entrance of the suction flotation machine through a pipeline to form a closed circuit. However, there are some obvious problems with the existing self-priming slurry feeding method of the collophanite tailings suction flotation machine.
[0003] First, when the foam tailings returned from the closed-circuit process of reverse flotation are connected to the slurry suction port of the flotation machine through a pipeline, the slurry cannot fill the pipe port at the slurry suction port, causing the flotation machine's suction capacity to be unbalanced, and then the slurry level of the flotation machine is unstable. This situation requires operators to make frequent adjustments, increasing workload and operating difficulty.
[0004] Secondly, when the foam from subsequent operations is directly returned to the flotation machine through the pipeline, the poor fluidity of the foam can easily cause the flotation machine to overflow, which not only affects the smoothness of the process, but also may cause waste in the production process and environmental pollution. Utility Model Content

This situation requires the operator to make frequent adjustments, which increases the workload and difficulty of operation. When the foam of the subsequent operation is directly returned to the flotation machine through the pipeline, due to the poor fluidity of the foam, it is easy to cause the flotation machine to overflow, which not only affects the smoothness of the process, but also may cause waste and environmental pollution in the production process.

This process system realizes closed-loop circulation treatment of tailings, reduces waste and environmental pollution in the production process, and improves resource utilization and the economic benefits of the enterprise.
