Problems solved by technology

Moreover, the Knox agent consumes quickly and is easily oxidized by the oxygen in the pulp and loses its inhibitory effect.
Other organic agents that have an inhibitory effect on copper sulfide ore, such as mercaptoacetate, ethyl mercaptan, etc., do not have industrial application prospects

Embodiment Construction

[0024] Specific embodiments of the present invention are embodied by the following drawings and their descriptions. A beneficiation agent and method for separating copper-molybdenum mixed concentrate. The beneficiation agent used for separation of copper-molybdenum mixed concentrate is any one of oxalic acid, water glass, sulfonated kerosene, ethylthiourethane or a combination thereof.

[0025] Molecular formula of oxalic acid: C6H8O7

[0026] Molecular formula of water glass: Na2SiO3.9H2O

[0027] Sulfonated kerosene: Sulfonated kerosene, also known as No. 260 solvent oil, is sulfonated kerosene. It is characterized by uniform and slow evaporation speed, less aromatic hydrocarbon content, low toxicity and high safety. No odor, pure quality, no residue after evaporation, not easy to oxidize when heated.

[0028] Molecular formula of ethylthiocarbamate (common name Z-200): (CH3)2CHOC(S)NHC2H5

[0029] According to per ton of copper-molybdenum mixed concentrate feed, the amo...

Abstract

The invention provides a beneficiation reagent and method for separating copper-molybdenum mixed concentrates. According to the invention, the effective separation of copper-molybdenum mixed concentrates can be realized by using a concentrated reagent removal and an oxalic acid reduction method, and the oxalic acid reduction method has an effective restraining effect on primary and secondary copper-sulphide ores such as chalcopyrite and chalcocite and the like, the process is simple and reasonable, and the recovery rate of molybdenum is high. The method disclosed by the invention concurrentlyhas the characteristics of good stability, strong adaptability and less reagent consumption, and can greatly reduce the production cost.

Description

1. Technical field [0001] The invention relates to a beneficiation agent and method for separating copper-molybdenum mixed concentrate, which is particularly suitable for separating copper and molybdenum metals from copper-molybdenum mixed concentrate. 2. Background technology [0002] At present, there are two separation processes for copper-molybdenum mixed concentrate: one is to suppress copper and float molybdenum; the other is to suppress molybdenum and float copper. The process of suppressing molybdenum and floating copper is complicated to operate, the cost is high, and the recovery rate of molybdenum is not high; the process of suppressing copper and floating molybdenum is widely used. For many years at home and abroad to suppress copper and float molybdenum, the following agents are usually used alone or in combination, such as sodium sulfide, sodium cyanide, Knox, etc. At present, the main methods used in China are sodium sulfide method and sodium cyanide method. ...
