Problems solved by technology
Since there are many useless coarse-grained hybrids participating in the grinding together, it will accelerate the wear speed of the mill lining and increase the loss of the grinding medium. In addition, the high fine-grained impurities produced by dissociation will also increase the pollution of the regenerated surface and reduce the purpose. Selectivity of minerals, reducing selectivity of sorting

The invention discloses a device and method for upgrading and dissociating coarse-grained minerals, which are suitable for being used in the field of mineral separation. The device comprises a funnel-shaped dehydration cone arranged at the bottom, wherein a tail hydraulic flotation separation unit barrel of a columnar structure is arranged on the dehydration cone, a lower opening of the tail hydraulic flotation separation unit barrel is connected with an upper opening of the dehydration cone in a matched mode, a circulating ore pulp distribution device is arranged between the tail hydraulic flotation separation unit barrel and the dehydration cone, the outer side of the upper part of the tail hydraulic flotation separation unit barrel is sleeved with an ore grinding dissociation unit barrel, and a dissociated concentrate discharging opening is formed in the upper portion of the side wall of the ore grinding dissociation unit barrel; a hydraulic flotation separation unit feeding port and a tailing discharging port are formed in the bottom of a funnel of the dehydration cone, and a water supplementing port is formed in the side wall, below the circulating ore pulp distributing device, of the top of the dehydration cone. Ore grinding products are high in quality, the dissociation effect is good, the process steps are simple, and newly-generated pollution is effectively reduced.
Description
technical field [0001] The invention relates to a dissociation device and method, in particular to a coarse mineral upgrading and dissociation device and method used in the field of mineral separation. Background technique [0002] In the process of mineral utilization, the separation and enrichment of useful minerals is a very important part. Most of the minerals are very finely distributed, and it is difficult to achieve fine separation by gravity separation. Therefore, mineral separation mainly adopts "dissociation + separation". Selected" the general process flow. As a prerequisite for mineral separation, dissociation directly affects the efficiency of subsequent processes. [0003] At present, the dissociation of coarse-grained minerals basically uses a mill, and the dissociated products are separated into components by flotation and other methods. Mills include many types such as rod mills and ball mills. Adding surface modifying agents during the grinding process ca...
