The collecting agent for the desiliconization of reverse flotation is suitable for separating the silicate minerals in a reverse flotation way from the iron ores of magnetite, hematite, ilmenite, etc., and ores containing the silicate minerals, such as bauxite ores, etc.
Description
[technical field] the present invention relates to a kind of Counterfloatating desiliconization with collecting agent and preparation method thereof, particularly at the Counterfloatating desiliconization of iron ore such as magnetic iron ore, bloodstone and ilmenite and bauxite.
The reverse floatation process that [background technology] is traditional comprises anion reverse floatation and cation-collecting agent reverse flotation.Anion reverse floatation is adjusted more than the pH to 11 with NaOH or sodium carbonate, with the quartzy eka-silicon hydrochlorate mineral of calcium ion (calcium chloride or calcium hydroxide) activation, carry out flotation with fatty acid collecting agent, suppress the purpose mineral with starch (tapioca, acorn starch and Semen Castaneae starch etc.), sulfonated lignin and dextrin etc.The shortcoming of this method is that medicament kind is many, the cost height, and environmental pollution is serious, and only is applicable to that grade is higher, the ore that the silicate gangue more easily floats.Cation-collecting agent reverse flotation scheme mainly suppresses the purpose mineral with waterglass, tannin, starch and sulfonated lignin etc.At pH is 8～9 o'clock, with silicate gangues such as amine collector flotation quartz.The characteristics of this method are: purpose mineral recovery rate and concentrate quality be all than the anion reverse floatation height, and generally can remove the desliming operation from.But the medicament kind of conventional cation reverse flotation technology is more, reagent cost height, production process complexity.Searching and development of new high-effective cationic collecting agent are the key points of reverse flotation technology.Wherein, comparatively outstanding with the research of quaternary ammonium salt surface active agent.At present, mainly contain about the example that uses quaternary ammonium compound to make collecting agent:
(1) disclose among the US 3 960 715 to relate to and comprising quaternary amine, for example DTAC is isolated the froth flotation method of silicon gangue component from iron ore under situation about existing in flotation collector at interior sun.
(2) announced among the CN 1347345A and have the iron ore precipitating reagent, and the pH value is under 7～11 the situation, to adopt to have R

Z-The quarternary ammonium salt compound of structure is made collecting agent in reverse floatation.
In above-mentioned disclosed patented technology, remain, or the concentrate mesosilicic acid salt content that obtains is too high, or the concentrate yield that obtains is too low, perhaps is applicable to the lower situation of silicon content in the ore, and all need to add other auxiliary adjustment agent in the floatation process in certain deficiency.
The problem that [summary of the invention] exists at existing quaternary ammonium salt cationic reverse floatation process, the invention provides a kind of under the prerequisite of not adding any adjustment agent (as starch, dextrin and tannin etc.), the efficient silicate mineral collecting agent of quaternary ammonium salt cationic with high selectivity, strong collecting ability is to be used for the reverse flotation silicate mineral.
Counterfloatating desiliconization collecting agent of the present invention belongs to compound quaternary cationic surfactant, and this cationic surfactant contains multiple functional group, wherein, mainly comprises following functional group:
Its anion can be the compound of halide such as Br, Cl etc.Outward appearance is pale yellow to white paste, and it is instant that normal temperature adds water, need not to add acid or heat treated.
The preparation method of collecting agent of the present invention is: with in the trimethyl halide of carbon containing 12 to 18 any, under 80 ℃ to 100 ℃ condition, be incubated 15 to 20 minutes, cool off then and stirred 10 to 15 minutes, it is light yellow to white paste that it is become, add in the dimethyl benzyl halide of carbon containing 12 to 18 any by weight 0.5～1: 1 ratio again, evenly stirred at normal temperatures 10 to 20 minutes, obtain collecting agent of the present invention.Add the halid ratio of dimethyl benzyl of carbon containing 12 to 18, according to handled ore different in kind and respective change.
Counterfloatating desiliconization collecting agent of the present invention has following characteristics: the carbochain of the preferred carbon containing 12 to 18 of its alkyl, and major function group is:
Figure and/or
Flotation to silicate mineral possesses high selectivity and strong collecting ability simultaneously, has remedied the defective that existing similar medicament only possesses the single performance of high selectivity or strong collecting ability; Have no side effect, belong to the environment-friendly type beneficiation reagent.
The preparation method of Counterfloatating desiliconization collecting agent of the present invention has following characteristics: preparation process is simple, and according to the difference of raw materials for production composition, the outward appearance of collecting agent of the present invention is light yellow to white thickness paste, and its conversion yield is 78%～90%; The preparation of medicament is simple, and it is instant to add water under the normal temperature, need not to add acid or heating preparation.
Adopt the floatation process of Counterfloatating desiliconization collecting agent of the present invention to have following characteristics: to be applicable to 4 ℃ to the 35 ℃ floatation process under the environment; The mash acid alkalinity scope that adapts to is pH=4～11, and raw meal particle size is-0.074mm 70% to 95% to need not predictive desliming and handle; Look the difference of the ore character of handling, can add or not add other and adjust agent (as starch etc.); According to the variation of ore mesosilicic acid salt mineral content, its consumption is between 80～500 gram/tons.
