Abstract
The invention discloses a flotation agent for copper-zinc separate flotation of a copper-zinc ore. The flotation agent is prepared from the following raw materials in parts by weight: 20-28 parts of xanthate, 30-50 parts of alkyl allyl sulfur ammonia ester, 1-2 parts of sodium hydroxide, 1-2 parts of sodium sulfide, 6-8 parts of isopropyl ethyl sulfur ammonia ester and 2-3 parts of copper sulfate. According to the flotation agent disclosed by the invention, the defects of the prior art are overcome, the collecting capacity is strong, but the collecting capacity on a zinc sulfide ore and an iron pyrite is weaker, the flotation agent is applied to the copper-zinc ore flotation, mutual containing of copper concentrate and zinc concentrate can be reduced, and the recovery rate of copper and zinc is increased by 1%-3%; by taking an ore dressing test of some copper-zinc ore (which includes 1.27% of copper, 3.59% of zinc and 23.35% of sulfur) in Sinkiang as an example and replacing conventional butyl xanthate and ester 105 by adopting the flotation agent, the grade of the copper concentrate is increased by 0.75%, and the recovery rate of the copper concentrate is increased by 1.65%; the grade of the zinc concentrate is increased by 2.50%, and the recovery rate of the zinc concentrate is increased by 1.02%.
Description
Technical field
The present invention relates to flotation agent technical field, belong to a kind of flotation agent of copper zinc ore copper-zinc separate flotation.
Background technology
Flotation is the difference utilizing mineral surfaces hydrophobic-hydrophilic, to a kind of method that mineral are processed.Utilizing the physical chemical differences of mineral surfaces to sort the process of mineral grain, be once called as floating separation, is most widely used beneficiation method.Nearly all ore all can use flotation sorting.As sulfide minerals such as gold mine, silver ore, galena, zincblende, chalcopyrite, vitreous copper, molybdenite, pentlandites, malachite, cerussite, smithsonite, smithsonite and bloodstone, cassiterite, wolframite, ilmenite, beryl, the sorting of spodumene and the oxide mineral such as rare-earth mineral, uranium ore.Sorting of the nonmetallic minerals such as graphite, sulphur, diamond, quartz, mica, feldspar and the nonmetal saline minerals such as silicate mineral and fluorite, apatite, barite and the solubility such as sylvite, rock salt saline minerals.Although utilize the hydrophobic nature of mineral also can carry out sorting of ore, usually all use floating agent to increase or to reduce the hydrophobicity of mineral surfaces, adjustment controls the flotation behavior of mineral.Flotation is suitable for process particulate and fine granule material, is difficult to reclaim the fine mineral particle being less than 10 μm, also can uses floatation process by other beneficiation methods.The flotation technology of some special disposal superfine particles, callable granularity lower limit is lower, and ultra-fine flotation and ion flotation technology can reclaim from colloidal solid to all kinds of materials being molecule, ionic condition.Flotation also can sort the intermediate products of pyrometallurgy, useful component in volatile matter and slag, the precipitated product of process hydrometallurgy leached mud and displacement, reclaims the inorganic matter in chemical products (as paper pulp, surface reactive material etc.) and waste water and organic matter.
Floating agent belongs in fact a special part of applied chemistry.Utilize chemicals, particularly organic chemical and specific mineral surfaces generation physics or the absorption of chemistry, reached the object be separated with other mineral or gangue by method for floating; Because copper Zn content is low in nature copper zn Mineral resource, by floatation process, the metal in ore must be carried out enrichment.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of flotation agent of copper zinc ore copper-zinc separate flotation is provided, be made up of the raw material of following weight portion: xanthate 20-28 part, polyoxyethylene base thiourethane 30-50 part, NaOH 1-2 part, vulcanized sodium 1-2 part, isopropoxyethyl radicals thiourethane 6-8 part, copper sulphate 2-3 part forms; This flotation agent is selective good to copper sulfide mineral, and collecting ability is strong, and to zinc sulfide ore and pyrite collecting ability more weak, it is applied to copper zinc ore floating, can reduce copper, zinc concentrate to contain mutually, improves copper, zinc recovery 1-3%.Be example with the beneficiation test of Xinjiang copper-zinc ore (cupric 1.27%, zinc 3.59%, sulphur 23.35%), adopt the flotation agent invented to substitute conventional butyl xanthate and ester 105, copper concentrate copper grade improves 0.75%, and the rate of recovery improves 1.65%; Zinc concentrate zinc grade improves 2.50%, and the rate of recovery improves 1.02%.
The present invention adopts following technical scheme to achieve these goals:
A flotation agent for copper zinc ore copper-zinc separate flotation, is made up of the raw material of following weight portion: xanthate 20-28 part, polyoxyethylene base thiourethane 30-50 part, NaOH 1-2 part, vulcanized sodium 1-2 part, isopropoxyethyl radicals thiourethane 6-8 part, copper sulphate 2-3 part.
Preferably be made up of the raw material of following weight portion; Xanthate 28 parts, polyoxyethylene base thiourethane 50 parts, 2 parts, NaOH, 2 parts, vulcanized sodium, isopropoxyethyl radicals thiourethane 8 parts, 3 parts, copper sulphate.
Described flotation agent is made into the aqueous solution that volume fraction is 37% when using, and mixing time is 10-15 minute.
Compared with the prior art, beneficial effect of the present invention is as follows:
The flotation agent of copper zinc ore copper-zinc separate flotation provided by the invention is selective good to copper sulfide mineral, collecting ability is strong, and to zinc sulfide ore and pyrite collecting ability more weak, it is applied to copper zinc ore floating, can copper be reduced, zinc concentrate contains mutually, improve copper, zinc recovery 1-3%.Be example with the beneficiation test of Xinjiang copper-zinc ore (cupric 1.27%, zinc 3.59%, sulphur 23.35%), adopt the flotation agent invented to substitute conventional butyl xanthate and ester 105, copper concentrate copper grade improves 0.75%, and the rate of recovery improves 1.65%; Zinc concentrate zinc grade improves 2.50%, and the rate of recovery improves 1.02%.
