Problems solved by technology

[0003] The main purpose of the present invention is to overcome the deficiencies in the prior art, and provide a method for pre-enrichment of copper-molybdenum ore, which is used to solve the problem of poor ore, refractory ore and co-associated ore. The quality content of the raw ore is low, and the separation is difficult. The traditional process crushes and grinds all the raw ore and then sorts it, resulting in a large equipment load rate and high beneficiation costs.

Abstract

The invention discloses a copper-molybdenum ore pre-enrichment method. The method comprises the steps that 1, crushing and then screening copper-molybdenum raw ore to obtain first-fraction ore, second-fraction ore and third-fraction ore; 2, returning the third-fraction ore to the crushing process, and separating the second-fraction ore through an X-ray radiation separator to obtain copper-molybdenum rough concentrate and copper-molybdenum rough tailings; 3, subjecting the copper-molybdenum rough concentrate to fine crushing and then screening to obtain first-fraction ore and second-fraction ore; and 4, returning the second-fraction ore to fine crushing procedure, and taking the first-fraction ore as pre-enriched copper-molybdenum ore to be stored. According to the method, the copper-molybdenum raw ore is screened according to different size fraction ranges after being crushed, and the pre-enriched copper-molybdenum ore is obtained by combining X-ray radiation separation, so that the recovery rate of copper and molybdenum is improved, the grade of the pre-enriched copper-molybdenum ore is further improved, the available copper-molybdenum raw ore reserve is increased, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of mineral processing, and in particular relates to a method for pre-enrichment of copper-molybdenum ore. Background technique [0002] Copper and molybdenum are important non-ferrous metals in my country. Because of their good physical and chemical properties such as high temperature resistance, good thermal conductivity and corrosion resistance, they are widely used in machinery manufacturing, medical treatment, chemical industry and other fields. In the world, copper-based and associated molybdenum deposits often exist in the form of porphyry-type copper deposits and skarn-type copper deposits, which are the main source of copper-molybdenum metals. This kind of minerals are mainly lean ore, refractory ore and associated ore. The mass content of copper and molybdenum is low, and the separation is difficult. The traditional process crushes and grinds all the raw ore and then sorts it. The equipment load rat...
