Abstract

The invention belongs to the technical field of mineral processing and particularly relates to a method for separating pre-concentrated copper gold by adopting X-ray radiation. The method comprises the steps as follows: crushing the copper gold to be less than 150 mm through a crushing machine; sieving the crushed material by a sieving machine with the mesh size of not less than 20 mm; feeding the sieved material onto an X-ray radiation separating machine through a feeding machine; setting a separating threshold value according to the content of copper in original mineral in a control system of the X-ray radiation separating machine; separating by the X-ray radiation separating machine; and separating out gold mineral concomitant with copper mineral to obtain gold concentrate and tailings. The method is domestically initiated, the target component of the treated mineral is low in quality, the mechanical and automatic level is high, the mineral separation cost is saved, the quality of the separated gold is greatly improved, and the utilization rate of equipment is remarkably increased; and meanwhile, the process technology is reasonable, the operation is stable, the copper gold pre-selection industrialization is facilitated, and the economic technical index and the comprehensive benefit of dressing plants are greatly increased.

Description

[0001] technical field

[0002] The invention belongs to the technical field of mineral processing, and in particular relates to a method for pre-enrichment of copper-bearing gold ore by adopting X-ray radiation sorting. Background technique

[0003] Because of its rarity, specialness and preciousness, gold has been regarded as the head of hardware since ancient times, and has the title of "King of Metals". Gold has the characteristics of good physical properties, stable chemical properties, high ductility, and scarcity. It is not only a special currency used for financial reserves and investment, but also an important currency in the jewelry industry, electronics industry, modern communications, and aerospace industries. important material for the department.

[0004] China is relatively rich in gold mine resources. There are 1,265 mining areas with proven reserves, and the total reserves are 4,265 tons, ranking seventh in the world. Among them, the associated gold res...
