Example Embodiment

[0018] Example 1

[0019] The molybdenum concentrate decarburization process of this embodiment includes replacement of flotation reagents, concentration, filter press and drying treatment; among them:

[0020] The specific process of replacing the flotation reagent is: replacing all the flotation reagents used in the process of molybdenum roughing, sweeping, beneficiation and fine sweeping with No. 200 solvent oil; the flotation reagents are collectors and dispersants. Foaming agent; after the replacement, the molybdenum-containing ore is roughed, scavenged, beneficiated and fine scavenged according to the conventional flotation process to obtain a water content of 85% (mass content) and a carbon content of 2.5% (mass Content) molybdenum concentrate foam;

[0021] The specific process of the concentration and filter press is: placing the molybdenum concentrate foam in a TNT-12 thickener for concentration treatment to obtain a slurry, and then sending the slurry to a LAROX-PF automa...

Abstract

The invention provides a molybdenum concentrate decarburization technique. The molybdenum concentrate decarburization technique comprises the steps that all flotation reagents used in the molybdenum flotation process are replaced by No. 200 megilp, concentration and filter pressing are conducted, and drying treatment is conducted. According to molybdenum concentrate treated through the technique, the mass content of molybdenum is no less than 57%, and the mass content of carbon is no greater than 0.5%. The problems that the carbon content in existing molybdenum concentrate exceeds the standard and the quality is unqualified are solved, the grade of the molybdenum concentrate is improved, the yield of the high-grade molybdenum concentrate is increased, qualified raw materials for downstream molybdenum processing and producing of high-purity molybdenum disulfide are provided, the molybdenum product types are increased, and the comprehensive benefits of molybdenum are increased.

Description

technical field [0001] The invention belongs to the technical field of molybdenum material processing, and in particular relates to a decarburization process of molybdenum concentrate. Background technique [0002] The grade of molybdenum concentrate produced by most domestic and international molybdenum concentrators is between 45% and 54%, and a few concentrators can produce 57% high-quality molybdenum concentrate. The production of high-purity molybdenum disulfide by molybdenum chemical industry has high requirements on the quality of molybdenum concentrate as raw material. It is required that the molybdenum grade in the molybdenum concentrate should not be less than 57%, and the carbon content should not exceed 0.5%. Due to changes in ore properties, the concentrator cannot guarantee continuous and stable mass production of molybdenum concentrates of more than 57% every day. Most of the molybdenum concentrate grades are around 56.5%. The carbon content in molybdenum con...
