Abstract

The invention discloses a method of floatation separation of a copper-molybdenum mixed concentrate containing hydrophobic ganguemicro-fine particles. The method comprises the following steps that slurry mixing of the fine copper-molybdenum mixed concentrate containing the hydrophobic ganguemicro-fine particles is conducted, ore pulp is carried out for copper and molybdenum for pre-separation and roughing to obtaina molybdenum coarse concentrate with a high copper content and rougher tailings1, the molybdenum coarse concentrate is grinded, the refined ore pulp is carried out for copper and molybdenum intensive separation flotation to obtain a copper molybdenum enhanced separation flotation molybdenum coarse concentrate and intensified separation rougher tailings2, separation and scavengingof the copper and the molybdenum are carried out after the combination of the rougher tailings1 and 2 to obtain a scavenging concentrate and a copper concentrate, the scavenging concentrate is returned to copper and molybdenum for pre-separation and roughing, the copper molybdenum enhanced separation flotation molybdenum coarse concentrate is carried out for five times of concentrated concentration, a molybdenum concentrate and five selected molybdenum middlingsare obtained, the selected middlingobtained fromthe first time returned to the copper and molybdenum pre-separation roughing operation, and the selected middlingsobtained from the next four timesreturn to the previous layer for operation in sequence respectively. The flotation separation methodhas the advantages ofhigh efficiency, stability, energy saving, environmental protection, economy, strong adaptability and good selection index.

Description

technical field [0001] The invention belongs to the technical field of mineral processing engineering, and relates to a flotation separation method of copper-molybdenum mixed concentrate, in particular to a flotation separation method of fine-grained copper-molybdenum mixed concentrate containing hydrophobic gangue. Background technique [0002] Molybdenum is an important rare metal, which is mainly extracted from molybdenite. At present, the proven molybdenum deposits in China are mainly porphyry-type copper-molybdenum deposits and skarn-type copper-molybdenum deposits, among which porphyry-type copper-molybdenum deposits are mostly with large reserves and low grade of associated molybdenum. For this kind of copper-molybdenum symbiotic ore, most of the domestic and foreign adopt the copper-molybdenum mixed floating process to obtain copper-molybdenum mixed concentrate, and then use the method of copper suppression and floating molybdenum to process, and finally obtain molyb...
