Cyclone and high-speed disc sorting machine combined desliming system and desliming process

Abstract

The invention discloses a cyclone and high-speed disc sorting machine combined desliming system and a desliming method which adopts the system. The system comprises a grinding system, a size mixing tank, a first valve, a mineral slurry pump, a cyclone, a slag insulation screen, a buffer barrel, a second valve, a transfer pump and a high-speed disc sorting machine. Firstly, obtained original minerals are ground to the target fineness, water is added so as to be adjusted to the required concentration, and then first-stage desliming is performed through the cyclone, so that second-stage deslimingis performed on overflow products by adopting the high-speed disc sorting machine. By adopting the system and the method, slime of which the particle size is less than 10 mum can be effectively removed, the amount of loss of useful mineral metal in the overflow products is less, and the subsequent recovery rate is greatly increased; after the effective desliming treatment, the quantity of minerals which enter the flotation operation in the next step is obviously reduced, the subsequent processing burden is reduced, and the mineral separation cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of mineral processing, and in particular relates to a cyclone-high-speed disc separator combined desliming system and a desliming process. For the molybdenum tungsten oxide ore with fine particle size and more easily muddifiable minerals, desliming is performed in advance. technical background [0002] Molybdenum and tungsten are important strategic resources in my country and are widely used in iron and steel metallurgy, chemical industry, aerospace, electronics and other technical fields. In recent years, with the reduction of high-quality molybdenum and tungsten resources, rich ore resources are increasingly exhausted, and various poor, fine and difficult-to-select molybdenum-tungsten ores have become the source of molybdenum and tungsten resources. However, in the process of processing, due to the fine particle size of the useful minerals, to recover the minerals, the minerals must be ground. The slime...

AI Technical Summary

Problems solved by technology

However, in the process of processing, due to the fine particle size of the useful minerals, to recover the minerals, the minerals must be ground. The slime content less than 10μm will greatly increase, which will have a serious impact on the separation accuracy, especially the separation accuracy of fine-grained materials, and seriously affect the subsequent flotation accuracy. It is necessary to have a large amount of ore embedded with fine particle size

[0003] At present, the main desliming processes are desliming hopper, multi-stage cyclone in series, etc. These processes have problems such as low desliming efficiency, low processing capacity, and high loss rate of useful minerals and metals. After the multi-stage cyclone is connected in series, although the improvement The desliming effect is improved, but the processing time is greatly increased, the operation is complicated, and the fine mud minerals removed contain more metal minerals. For poor, fine, and difficult-to-select mines, the loss is greater, resulting in the loss of metal minerals. Serious loss and waste

That is to say, the existing treatment process can not achieve high treatment efficiency while increasing the treatment process before flotation, resulting in a greatly reduced technical and economic index of mineral processing
