Abstract

The invention discloses a molybdenum multi-metal sulfide ore flotation separation inhibitor and a flotation separation method thereof. A preparation method of the molybdenum multi-metal sulfide ore flotation separation inhibitor comprises the steps: putting acrylamide and allyl thiourea into an organic solvent, carrying out copolymerization reaction under the initiation of an oil-soluble initiator, setting the temperature to be 50-90 DEG C, and carrying out a reaction for 1-10 h to obtain the molybdenum multi-metal sulfide ore flotation separation inhibitor. Effective separation of the molybdenum multi-metal sulfide ore can be achieved, the comprehensive recycling rate of molybdenum is increased, the content of impurities such as copper, lead, sulfur and bismuth in molybdenum concentrate is reduced to the maximum extent, raw materials are easy to obtain, the preparation process is simple, use is safe, toxicity is low, and harm to human bodies and the environment is avoided.

Description

technical field

[0001] The invention relates to a molybdenum polymetallic sulfide ore flotation separation inhibitor and a flotation separation method thereof, belonging to the technical field of molybdenum polymetallic sulfide ore beneficiation. Background technique

[0002] Flotation is one of the most commonly used and effective methods in the processing of mineral resources. It can effectively separate hydrophobic particles (such as valuable minerals) from hydrophilic particles (such as gangue minerals), so as to achieve efficient and comprehensive utilization of valuable minerals. Purpose. In the separation of complex and refractory molybdenum polymetallic sulfide ores, the flotation separation of molybdenite and other sulfide ores has always been a difficult problem.

[0003] my country's molybdenum resource reserves are relatively rich, but the grade is generally low, and it is often associated with copper, lead, zinc, bismuth, sulfur and other metal sulfide ores (so...
