Problems solved by technology

[0003] At present, the separation methods of copper-molybdenum sulfide mixed concentrate at home and abroad mainly include flotation separation method, and the copper-molybdenum flotation separation method mainly has the following defects: 1. The mixed concentrate is pre-removed, which increases the complexity of the process, and at the same time It will cause "secondary pollution" and affect the subsequent separation; 2. The molybdenite mosaic particle size is generally fine, and the fin

Embodiment 1

[0025] Copper grade of copper molybdenum sulfide mixed concentrate is 21.52%, molybdenum grade is 2.93%, the content of chalcopyrite and bornite in copper minerals in copper minerals (that is, the total content of both chalcopyrite and bornite) The content of molybdenite in molybdenum minerals is 94.7%, the content of molybdenite in molybdenum minerals is 98.3%, the ore with fineness less than 74μm in copper sulfide molybdenum mixed concentrate accounts for 86%, and the monomer dissociation degree of copper minerals and molybdenum minerals is 96.5%. .

[0026] The magnetic separation process is as figure 2 As shown, the copper-molybdenum mixed concentrate slurry is adjusted to a pulp concentration of 15% to obtain a copper-molybdenum mixed concentrate slurry, and then an ultrasonic disperser is used to ultrasonically disperse the copper-molybdenum mixed concentrate slurry to make the copper-molybdenum mixed concentrate slurry The copper-molybdenum ore particles in the medium...

Embodiment 2

[0032] The copper grade of copper-molybdenum sulfide mixed concentrate is 18.55%, the grade of molybdenum is 5.60%, the content of chalcopyrite and bornite in copper minerals (that is, the total content of chalcopyrite and bornite) is 93%, and the The content of molybdenite in the mineral is 96%, the copper-molybdenum mixed concentrate ore with a fineness less than 74μm accounts for 88%, and the monomer dissociation degree of copper mineral and molybdenum mineral is 96%.

[0033] The mixed copper-molybdenum sulfide concentrate is slurried until the concentration of the pulp is 15%, and the copper-molybdenum mixed concentrate slurry is obtained, and then the copper-molybdenum mixed concentrate slurry is ultrasonically dispersed by an ultrasonic disperser to make the copper-molybdenum mixed concentrate slurry The copper-molybdenum ore particles are dispersed to eliminate the agglomeration between the copper-molybdenum ore particles. The magnetic field strength of the high-gradien...

Abstract

The invention discloses an ultrasonic dispersing-magnetic separating process for copper-molybdenum bulk concentrate. The ultrasonic dispersing-magnetic separating process for the copper-molybdenum bulk concentrate includes the following steps that a, pulp conditioning is conducted, specifically, the copper-molybdenum bulk concentrate is subjected to pulp conditioning to obtain copper-molybdenum bulk concentrate pulp; b, ultrasonic dispersing is conducted, specifically, an ultrasonic dispersing instrument is used for conducting ultrasonic dispersing on the copper-molybdenum bulk concentrate pulp, so that copper-molybdenum ore particles in the copper-molybdenum bulk concentrate pulp are dispersed, and agglomeration among the copper-molybdenum ore particles is eliminated; c, magnetic separation and roughing of copper are conducted, specifically, a magnetic separator is used for conducting magnetic separation and roughing of copper on the copper-molybdenum bulk concentrate pulp after the particle dispersing step, so that copper roughing concentrate and copper roughing tailings are obtained; d, magnetic separation and scavenging of copper are conducted, specifically, the magnetic separator is used for conducting magnetic separation and scavenging of copper on the copper roughing tailings, so that copper scavenging concentrate and copper scavenging tailings are obtained, and the copper scavenging tailings are molybdenum concentrate; and e, magnetic separation and concentration of copper are conducted, specifically, the copper roughing concentrate is subjected to magnetic separation and concentration of copper, so that copper middling and copper concentrate are obtained.

Description

technical field [0001] The invention relates to the technical field of mineral separation, in particular to a copper-molybdenum mixed concentrate ultrasonic dispersion-magnetic separation separation process. Background technique [0002] There are few single molybdenum deposits in my country, and a large part of molybdenum deposits are associated with porphyry copper deposits. In porphyry copper deposits, copper and molybdenum minerals are densely symbiotic, with complex structures, uneven particle size distribution, and similar buoyancy of copper and molybdenum. , the separation of copper and molybdenum is difficult. [0003] At present, the separation methods of copper-molybdenum sulfide mixed concentrate at home and abroad mainly include flotation separation method, and the copper-molybdenum flotation separation method mainly has the following defects: 1. The mixed concentrate is pre-removed, which increases the complexity of the process, and at the same time It will caus...
