The application of infrared spectroscopy technique, analyzed the infrared spectra of A and B before and after chalcopyrite and restrained the role of agent of chalcopyrite. Research note: a chalcopyrite and B sodium thioglycolate and chalcopyrite produced by chemical adsorption dominated the adsorption effect and selective restraint on chalcopyrite; QY and chalcopyrite a, chalcopyrite B produced by chemical absorption and strong adsorption action, through thermodynamics analysis also proves this point is to simply can split off the QY of chalcopyrite also has a wide range of restraint function.
To improve the ore dressing skills of copper molybdenum ore in our country, and to stop the separation of copper and molybdenum ores, and to have the important economic value and practical significance to the sustainable development of the economy.
According to the different origin of chalcopyrite, selection of three kinds of representative copper preparation, through the process of pure minerals flotation experiments and practical ore flotation experiment, combined with infrared spectrum analysis technique, XRD testing modern testing techniques, and explore for more friendly anti copper agent, to open up, copper and molybdenum are copper sulfide restraint agent has certain reference value. At the same time, also made in copper containing copper concentrate, copper recycling rate reached 50.01.
The Xinjiang some copper containing 17.70, containing molybdenum 0.70 copper molybdenum concentrate of copper and molybdenum, respectively open demonstration experiment, obtained the molybdenum containing 51.51, containing copper 0.37, molybdenum accept rate was 59.97 molybdenum concentrate containing copper, copper rate was 82.07 copper concentrate.
