An automatic mineral separation equipment for refining tungsten ore

Abstract

The invention relates to the field of tungsten ore refining, in particular to a piece of automatic mineral separation equipment for tungsten ore refining. The equipment comprises a main case, a coarsescreening mechanism and a first fine screening magnetic roller. An ore feeding hopper is arranged on the top of the main case. The coarse screening mechanism is arranged in the main case, and the screening end thereof is inclined downward. The first fine screening magnetic roller is arranged below the screening end of the coarse screening mechanism. A rescreening mechanism parallel to the coarsescreening mechanism is arranged below the first fine screening magnetic roller. A second fine screening magnetic roller is arranged beside the upper end of the rescreening mechanism. A material passing plate extending towards the direction of the second fine screening magnetic roller is arranged at the screening end of the coarse screening mechanism. The two ends of the first fine screening magnetic roller penetrate to the outsides of the two sides of the main case, and a first motor in transmission connection with the first fine screening magnetic roller is arranged at one end. A set of discharging mechanisms in transmission connection with the first fine screening magnetic roller is arranged outside the two ends of the first fine screening magnetic roller. A second motor in transmissionconnection with the second fine screening magnetic roller is arranged at one end of the second fine screening magnetic roller. The equipment of the invention can improve the production quality of oreconcentrate.

Description

technical field [0001] The invention relates to the field of refining tungsten ore, in particular to an automatic mineral separation device for refining tungsten ore. Background technique [0002] Tungsten ore is the most important ore for extracting tungsten. It is also called wolframite. Because it contains different proportions of iron tungstate and manganese tungstate, if the iron content is higher, it is called wolframite, and it contains more manganese. It is called tungsten ore; tungsten ore is brown to black, with metallic or semi-metallic luster. Generally, it is produced in granite and quartz ore together with tin ore. For the current mining process of tungsten ore, the traditional tungsten ore separation process is Mainly "crushing and grading, manual hand-selected tailings, ore grinding, and re-election", although this process method is simple, it requires a lot of labor; later, automatic beneficiation equipment was gradually adopted, and magnetic separators were...

AI Technical Summary

Problems solved by technology

[0003] Existing magnetic separators are relatively weak in refining tungsten ore, because during the magnetic separation process, there are more concentrates in the tailings, and there will be more tailings in the concentrates , which will lead to a significant reduction in the quality of the concentrate, making it difficult to obtain satisfactory beneficiation technical indicators
