Wolframite tailing discarding and refining beneficiation method

Abstract

The invention discloses a wolframite tailing discarding and refining beneficiation method. The method aims to solve the technical problems that an existing wolframite beneficiation method is high in manpower cost and low in labor operation efficiency. The method comprises the steps that single-stage crushing grading operation is adopted to meet the fraction requirement of subsequent-stage tailingdiscarding operation; then an X-ray intelligent concentrating machine is adopted to perform sorting operation, metallic minerals and non-metallic minerals are separated, and large-yield direct tailingdiscarding of 6-50mm large-fraction minerals is realized; next, a high-pressure roller mill is adopted to make the granularity of broken minerals below 6.0mm; and then a coarse-particle ultrahigh-field-intensity vertical-ring high-gradient magnetic separator is used to perform one-roughening-one-sweeping sorting operation, and by use of super-strong magnetic force of the ultrahigh-field-intensityvertical-ring high-gradient magnetic separator, weakly-magnetic wolframite is effectively recovered, and meanwhile direct tailing discarding of coarse-particle minerals is further realized. Through the method, the large-fraction minerals can be subject to direct tailing discarding, the burden on subsequent operation can be greatly relieved, therefore, the beneficiation cost of wolframite is substantially lowered, and low-energy-consumption high-efficiency recovery of wolframite is realized.

Description

Technical field [0001] The invention belongs to the technical field of wolframite beneficiation, and specifically relates to a beneficiation method for tailing and refined wolframite, in particular to an X-ray intelligent concentrator and a coarse particle ultra-high field strength vertical ring high gradient magnetic separator Joint sorting method. Background technique [0002] Wolframite 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, which contains more manganese. Some are called wolframite; wolframite is brown to black with metallic or semi-metallic luster. Generally, it is produced in granite and quartz ore together with tin ore. [0003] Aiming at the current mining process of wolframite, the traditional separation process of wolframite is mainly based on "crushing ore classification, manual selection an...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the object of the present invention is to provide a mineral processing method for wolframite by throwing tails and extracting fines. Technical problem: This mineral processing method can directly throw the tailings of coarse-grained minerals, which can greatly reduce the burden of subsequent operations, thereby greatly reducing the processing cost of wolframite, and realizing low-energy and efficient recovery of wolframite
