Embodiment 1

[0034] A kind of iron ore flotation anion collector of the present invention, this collector is formulated by the component of following quality: 32g of hydroxy peroxide monoethanolamine, hogwash oil monoethanolamine 8g, 8-hydroxyquinoline 10g, cyclodextrin 10g, cetyl alcohol 15g, emulsifier OP-10 2g and water 23g.

[0035] The specific preparation method of the collector in this embodiment is: first synthesize the main agent of hydroxy peroxy oleic acid monoethanolamine and hogwash oil monoethanolamine through organic reaction, and then combine 35 g of hydroxy peroxy oleic acid monoethanolamine and hogwash oil monoethanolamine with the above-mentioned mass The rest of the components (namely adjuvant) are mixed and stirred evenly to obtain the microemulsion type collector of the present invention (number RA-925).

[0036] The application method of the collector in this embodiment is: first dilute the above-mentioned collector with water into a collector solution with a mass co...

Embodiment 2

[0043] An anion collector for iron ore flotation of the present invention, the collector is mainly prepared from the following components: C3 ~ C22 linear and / or branched mixed hydroxy fatty acid diethanolamine 47g, 4-methyl -8-hydroxyquinoline 5g, B-cyclodextrin 5g, oxidized kerosene 13g, diesel oil 5g, emulsifier SP-80 3g and water 22g. (No. RA-935)

[0044] The specific preparation method of the collector in this example is: first synthesize 47g of C3~C22 straight chain and / or branched chain mixed hydroxyl fatty acid diethanolamine main agent through organic reaction, and then C3~C22 straight chain and / or branched mixed hydroxyl 47g of fatty acid diethanolamine is mixed with the rest of the above-mentioned quality components (ie adjuvant) and stirred evenly to obtain the microemulsion type collector of the present invention. The preparation process produces no waste gas, waste water and waste residue.

[0045] The application method of the collector in this embodiment i...

Embodiment 3

[0051] A kind of iron ore flotation anion collector of the present invention, this collector is mainly formulated by the following components of quality: 53g of hydroxysoyate triethanolamine, 3g of 6-methyl-8-hydroxyquinoline, γ - Cyclodextrin 2g, myristyl alcohol 10g, diesel oil 7g, emulsifier Triton 100 5g and water 20g (code RA-945).

[0052] The specific preparation method of the collector in this example is as follows: first synthesize the main agent of oxidized hydroxysoyate triethanolamine through organic reaction, and then mix 53 g of the main agent hydroxysoyate triethanolamine with the remaining components (i.e. auxiliary agents) of the above quality, And stir evenly, make the collector of microemulsion type of the present invention.

[0053] The application method of the collector in this example is as follows: first dilute the above-mentioned collector with water into a collector solution with a mass concentration of 2%, and then use the collector solution as taili...

Abstract

The invention relates to an iron mine and oxidized ore beneficiation and flotation agent and a production method thereof and specifically discloses an iron ore and oxidized mine flotation anion collector; the main preparing agents of the anion collector are fatty acid modifier and derivatives thereof; assisting agents of the collector also comprise fatty alcohol, emulsifier and water. The production method of the collector comprises the following steps of compounding the main agents by organic action, then weighting rest components according to certain mass fractions, mixing according to a certain sequence, and uniformly stirring to prepare the micro-emulsion homogeneous phase viscous liquid. The collector has the advantages of strong collecting capacity, strong argillization resistance, low production cost, hard water resistance, stable performances, small agent use level, good selectivity, environment friendliness, safety and adaptivity to low temperature. By changing the variety and use level of the main agents, the series of collectors can be used for the flotation of diversified iron mines, phosphorite mines, fluorites, tungsten mines, rare earth mines, ilmenites and diversified oxidized mines.

Description

technical field [0001] The invention belongs to the technical field of high-efficiency utilization of mineral resources, and in particular relates to a flotation reagent for beneficiation of iron ore and various oxidized ores, a preparation method and application thereof. Background technique [0002] Mineral resources are one-time resources and are non-renewable. Due to years of mining and utilization, all kinds of rich ore resources in the world are decreasing day by day. Refractory minerals will become more and more important. Most ore resources in my country generally have the characteristics of "poor, fine, miscellaneous" and high impurity content, while high-quality "ore concentrate" has broad application prospects and broad market prospects, which objectively requires the concentrator to choose a reasonable capture Collector and its flotation process to produce high-quality concentrate, so as to achieve maximum economic benefits and save resources. Not only that, hig...
