[0002] Ore dressing is a process of crushing and grinding the ore according to the physical and chemical properties of different minerals in the ore, and then using gravity separation, flotation, magnetic separation, electrostatic separation and other methods to separate useful minerals from gangue minerals, and to separate various symbiotic useful minerals from each other as much as possible, and to remove or reduce harmful impurities, so as to obtain the raw materials required for smelting or other industries. Ore dressing can enrich the useful components in the minerals, reduce the consumption of fuel and transportation in smelting or other processing, and make low-grade ores economically utilized. After beneficiation of gold-containing ores, the tailings or concentrates need to be dehydrated.

[0003] After searching, the utility model patent with announcement number CN214513184U discloses a waste slag dehydration device for mineral processing, including an outer barrel body, the outer portion of the outer barrel body is cylindrical, and one end of the outer barrel body is open, and a symmetrical filter barrel mounting bearing is arranged inside the outer barrel body, and a filter barrel is rotatably arranged on the inner side of the filter barrel mounting bearing, and a reducer is arranged on the outer wall of the outer barrel body, and a first drive motor is arranged on the outer side of the reducer, and the reducer is connected to the outer wall of the filter barrel through a transmission shaft, and a water guide shell is arranged below the outer barrel body, and a second drive motor is arranged on the outer wall of the water guide shell, and the rotating shaft of the second drive motor is connected to a material extrusion rod through a coupling, and the material extrusion rod is in the water guide shell; the internal centrifugal filtering structure of the waste slag dehydration device for mineral processing can quickly separate the water in the waste slag, and the device is provided with an extrusion structure, which can extrude and separate the suspended matter in the wastewater to improve the separation effect of water and waste slag.

For this reason, we propose a wastewater dehydrator for mineral processing. Utility Model Content
