Abstract

The invention relates to an ore pre-enrichment control method, system, device and equipment based on face-to-face electrodes, and the control method comprises the following steps: generating a uniform electric field by adopting parallel electrodes of a face-to-face structure, and selectively crushing uniformly mixed particles by fully utilizing high-voltage electricity; according to the method, useful ore particles are selectively crushed without crushing gangue particles, then useful ore is collected by adopting a screening device, and useless gangue particles are discarded, so that pre-enrichment of useful metal ore particles is realized; according to the control method, only useful ore is subjected to pulse crushing, gangue is not damaged, the unit energy consumption of high-voltage electricity can be greatly reduced, and generation of tailings is reduced; the failure of execution equipment caused by the crushing of the gangue particles is avoided, and the production efficiency is also improved. The technical problems that the failure rate of execution equipment is high, more tailings are generated and the production efficiency is low in an existing metal ore pre-enrichment manufacturing process are solved.

Description

technical field [0001] The present application relates to the technical field of mineral processing, in particular to a method, system, device and equipment for controlling ore pre-enrichment based on surface-to-surface electrodes. Background technique [0002] At present, one of the problems faced by metal ore beneficiation is the decreasing raw ore grade. In order to meet the strong demand for metal ore in social development, mining enterprises can only continuously increase the processing capacity of raw ore. However, the method of increasing the processing capacity of raw ore seriously reduces the production efficiency of ore dressing, and at the same time produces a large amount of tailings, which brings huge pressure to environmental governance. [0003] Therefore, how to eliminate the useless gangue particles as much as possible before the ore is sent into the mill, without crushing the gangue particles, so as to realize the pre-enrichment of useful ore is an effectiv...
