Abstract
The invention discloses a lindgrenite flotation agent and usage thereof. The lindgrenite flotation agent is made from the following materials in part by weight: 10 to 20 parts of diesel oil mixture, 10 to 20 parts of kerosene, 2 to 5 parts of sodium sulphide and 1 to 1.5 parts of phthalate. The usage is as follows: raw ores are ground into negative 0.074mm, and account for 72 to 75 percent, the pulp density is 35 to 40 percent, and 100 to 110 grams/ton of flotation agent is added for molybdenum-copper mixture roughing, so that molybdenum-copper mixture rough concentrate and molybdenum-copper mixture rougher tailings are obtained; 60 to 70 grams/ton of flotation agent is added into the molybdenum-copper mixture rougher tailings for primary scavenging; 55 to 65 grams/ton of flotation agent is added for secondary scavenging, so that flotation tailings are obtained. The invention intends to overcome the defects of the prior art, and utilizes the different floatabilities of lindgrenite, sulfur and the like and the excellent selectivity of the agent to carry out the floatation and separation of the lindgrenite, so that high-quality molybdenum concentrate and high-quality copper concentrate are respectively obtained.
Description
Technical field
The present invention relates to and select agent and using method technical field thereof, belong to a kind of lindgernite flotation agent and using method thereof.
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.
Lindgernite is a kind of mineral resources of preciousness, wherein with the title lindgernite of molybdenum ore for main association copper mine.In general, in lindgernite, molybdenum grade is 0.04 ~ 0.10%, the content of association copper be 0.01 ~ 0.10% lindgernite belong to low-grade lindgernite.At present, because molybdenum copper content is too low or impurity content is high, low-grade lindgernite fails well to be developed.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of lindgernite flotation agent and using method thereof are provided, are made up of the raw material of following weight portion: diesel fuel mixtures 18 parts, kerosene 17 parts, 3 parts, vulcanized sodium, phthalic acid ester 1.2 parts composition; Using method: raw ore is milled to-0.074mm and accounts for 72 ~ 75%, pulp density 35 ~ 40%, adds flotation agent 100 ~ 110 grams/ton and carries out the mixing of molybdenum copper and roughly select, obtain molybdenum copper mixed crude concentrate and molybdenum copper mixing rougher tailings; Add flotation agent 60 ~ 70 grams/ton in molybdenum copper mixing rougher tailings and carry out once purging selection; Add flotation agent 55 ~ 65 grams/ton to carry out secondary and scan, obtain flotation tailing; Be a kind of lindgernite floatation process being core with novel compositions flotation agent, utilize the fine selectivity of the lindgernite floatability different from sulphur etc. and medicament carry out the flotation of lindgernite and be separated, obtain molybdenum concntrate and the copper concentrate of higher quality respectively.
The present invention adopts following technical scheme to achieve these goals:
A kind of lindgernite flotation agent and using method thereof, described flotation agent is made up of the raw material of following weight portion: diesel fuel mixtures 10 ~ 20 parts, kerosene 10 ~ 20 parts, 2 ~ 5 parts, vulcanized sodium, phthalic acid ester 1 ~ 1.5 part; Described using method: raw ore is milled to-0.074mm and accounts for 72 ~ 75%, pulp density 35 ~ 40%, adds flotation agent 100 ~ 110 grams/ton and carries out the mixing of molybdenum copper and roughly select, obtain molybdenum copper mixed crude concentrate and molybdenum copper mixing rougher tailings; Add flotation agent 60 ~ 70 grams/ton in molybdenum copper mixing rougher tailings and carry out once purging selection; Add flotation agent 55 ~ 65 grams/ton to carry out secondary and scan, obtain flotation tailing.
Preferably be made up of the raw material of following weight portion: diesel fuel mixtures 18 parts, kerosene 17 parts, 3 parts, vulcanized sodium, phthalic acid ester 1.2 parts.
Compared with the prior art, beneficial effect of the present invention is as follows:
Lindgernite flotation agent of the present invention and using method thereof, it is a kind of lindgernite floatation process being core with novel compositions flotation agent, utilize the fine selectivity of the lindgernite floatability different from sulphur etc. and medicament carry out the flotation of lindgernite and be separated, obtain molybdenum concntrate and the copper concentrate of higher quality respectively.
