Abstract

The invention discloses a polymetallic sulfide ore flotation separation inhibitor and a flotation separation method thereof; polymaleic anhydride reacts with an organic compound containing a pluralityof amino groups to obtain an intermediate M, and then the intermediate M reacts with carbon disulfide in an alkaline solution to obtain a polymetallic sulfide ore flotation separation inhibitor. Themulti-metal sulfide ore flotation separation inhibitor provided by the invention is simple in preparation process and mild in reaction condition, has the advantages of safety in use, convenience in addition, easiness in obtaining raw materials and the like, also has the technical advantages of low toxicity, environmental friendliness, small dosage and good inhibition effect, and can effectively replace a traditional inhibitor. The multi-metal sulfide ore flotation separation inhibitor can effectively inhibit impurity minerals such as galena, chalcopyrite, sphalerite, pyrite and bismuthite, canbe widely applied to the flotation separation process of multi-metal sulfide ores such as copper lead, lead zinc, molybdenum lead, molybdenum sulfur, molybdenum bismuth, copper molybdenum and copperlead molybdenum, and is beneficial to improving the separation index.

Description

technical field

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

[0002] Mineral resources play a vital role in the development of the national economy. The copper, lead, zinc, molybdenum and other non-ferrous metals extracted from them have made great contributions to the development of the national economy and are widely used in aerospace, electronic technology, High-performance materials, defense technology and other fields. However, the efficient and comprehensive utilization of refractory polymetallic resources has not been effectively solved, such as refractory polymetallic resources of copper, lead and zinc, and refractory polymetallic resources of molybdenum.

[0003] Flotation is one of the most commonly used methods in the processing of mineral resources. In the process of copper-lead...
