Problems solved by technology

In addition to the adjustment of the particle size distribution and surface physical properties of the input and output of the grinding equipment, the mineral grade does not change, and non-selective grinding will lead to rapid loss of the mill lining and grinding media, and will also increase regeneration Surface contamination reduces the selectivity of target minerals and reduces the selectivity of sorting

Abstract

The invention discloses a tailing discarding and dissociation integrated coarse grain mineral dissociation device and method, which are applicable to the field of mineral separation. The device comprises a hydraulic flotation separation unit and a stirring type ball milling unit, wherein the hydraulic flotation separation unit is located on the outer layer, the stirring type ball milling unit is arranged in the hydraulic flotation separation unit, an interlayer is arranged in the middle to allow concentrate in the hydraulic flotation separation unit to overflow and then feed the concentrate from the bottom of the stirring type ball milling unit. According to the invention, the hydraulic flotation separation unit plays a role in pre-discharging gangue, and a large amount of high-density gangue is discharged, so that the concentrate grade is improved; and the stirring type ball milling unit plays a role in dissociating coarse-grained minerals, releases more concentrates, and has the advantages of being high in ore milling product quality, simplifying the process and reducing new surface pollution.

Description

technical field [0001] The invention relates to a coarse-grained mineral dissociation device and method, and is especially suitable for a coarse-grained mineral dissociation device and method which are used in the field of mineral separation and which integrate tailing and dissociation. Background technique [0002] In the process of mineral utilization, the sorting and enrichment of useful minerals is a very important step. Most minerals are embedded with very fine particle size, and it is difficult to achieve fine separation by gravity separation. Therefore, mineral sorting mainly adopts "dissociation + sorting" "The general process flow. As a prerequisite for mineral separation, dissociation directly affects the efficiency of subsequent processes. [0003] At present, the dissociation of minerals is usually completed by crushers and mills. The crushers break large minerals into coarse-grained minerals. The products of the crushers are deeply dissociated through the mills...
