Description
Technical field
The present invention relates to a kind of collecting agent preparation method, relate in particular to a kind of collecting agent preparation method who is applicable to the flotation of bauxite coarse granule.
Background technology
In China, bauxite is taking diaspore type as main, its principal character is that the embedding cloth between high alumina, high silicon, low alumina-silica ratio, siliceous gangue mineral composition complexity, aluminum-containing mineral and siliceous mineral is in close relations, and this causes the production procedure of current China aluminium oxide long, energy consumption is high, cost is high.Along with the proposition of this technology of ore dressing-Bayer process, application beneficiation method constantly obtains and expands and go deep into the research of bauxite desiliconization in advance.Selective milling-aggregative flotation the technique proposing according to Central South University, within 2003, Chinese seat of honour 3000t/d ore concentration of bauxite factory is constructed and put into operation in Central Region, Henan aluminium manufacturer.
Along with the continuous decrease for ore deposit alumina silica ratio, directly on the low side as the alumina silica ratio of concentrate part by selective milling at present, and then cause the concentrate alumina silica ratio problem on the low side of whole technological process output just to reveal.Therefore original technological process is optimized, to improve the alumina silica ratio of concentrate, reduces beneficiation cost, just become Liquor of Ore Dressing Bayer process whether can there is the key point of advantage.And current applied collecting agent mostly is fatty acid collecting agent, it is better to fine grain collecting effect, but very limited for its collecting effect of coarse granule, therefore, in order to improve the alumina silica ratio of coarse granule mineral, the collecting agent of development of new becomes the key of dealing with problems.
Summary of the invention
The invention provides a kind of collecting agent preparation method who is applicable to the flotation of bauxite coarse granule in order to solve the problems of the technologies described above, object is the collecting ability that strengthens collecting agent.
Be applicable to the collecting agent preparation method of bauxite coarse granule flotation for reaching above-mentioned purpose the present invention, comprise the steps: by tall oil to be that 1:0.5-5 mixes with glacial acetic acid according to volume ratio, after boiling 2 h-4 h, reflux, product filters while hot, and filtrate is placed crystallization; Crystallized product with iodine react at 50 DEG C-100 DEG C, reaction is filtered after 0.5 h-2 h; Filtration product is dissolved in benzole soln, slowly adds the concentrated sulfuric acid, after stirring 2 h-5 h, it is reacted completely; Products therefrom is neutralized to alkalescence with soda lye, has both obtained required collecting agent.
Described filtrate is placed and is carried out crystallization at 10 DEG C-30 DEG C.
Described crystallized product is resin acid.
What described filtration obtained is oxidation product.
Described filtration product is dissolved in benzole soln and obtains mixture.
Described mixture and strong sulfuric acid response obtain sulfonated products.
Advantageous effect of the present invention: compare with traditional fatty acid collecting agent and there is larger cross dimensions and stronger hydrophobicity, on molecule, obtain two oxygen atoms and can form two ring chelates by the aluminium atom of chemical bond and mineral surfaces, increase the stability of combination; And binary cyclic group has stronger hydrophobicity.Therefore can there is good collecting ability to coarse granule bauxite.Simultaneously selected tall oil extensive, the cheap feature that has selection, can effectively reduce the cost of bauxite flotation process Chinese medicine.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
Embodiment 1
The present invention is applicable to the collecting agent preparation method of bauxite coarse granule flotation as shown in the figure, comprises the steps: by tall oil to be that 1:0.5 mixes with glacial acetic acid according to volume ratio, refluxes after boiling 2h, and product filters while hot, and filtrate is placed crystallization; Crystallized product with iodine react at 100 DEG C, reaction is filtered after 0.5h; Filtration product is dissolved in benzole soln, slowly adds the concentrated sulfuric acid, after stirring 2h, it is reacted completely; Products therefrom is neutralized to alkalescence with soda lye, has both obtained required collecting agent.Filtrate is at room temperature placed and is carried out crystallization.Crystallized product is resin acid.What filtration obtained is oxidation product.Filtration product is dissolved in benzole soln and obtains mixture.Mixture and strong sulfuric acid response obtain sulfonated products.
Embodiment 2
Be that 1:5 mix with glacial acetic acid according to volume ratio by tall oil, reflux after boiling 3h, product filters while hot, and filtrate is placed crystallization; Crystallized product with iodine react at 80 DEG C, reaction is filtered after 2h; Filtration product is dissolved in benzole soln, slowly adds the concentrated sulfuric acid, after stirring 3 h, it is reacted completely, and filtrate is placed crystallization at 10 DEG C.The other the same as in Example 1.
Embodiment 3
Be that 1:2 mix with glacial acetic acid according to volume ratio by tall oil, reflux after boiling 4h, product filters while hot, and filtrate is placed crystallization; Crystallized product with iodine react at 50 DEG C, reaction is filtered after 1h; Filtration product is dissolved in benzole soln, slowly adds the concentrated sulfuric acid, after stirring 5h, it is reacted completely, and filtrate is placed crystallization at 30 DEG C.The other the same as in Example 1.
The reason that collecting agent is improved bauxite forward flotation effect is that tall oil is partially oxidized.The oxidized process of tall oil is a kind of radical reaction simultaneously, can produce certain impact to floatation process, has strengthened its collecting ability.Simultaneously also to have stability strong for collecting agent, be difficult for oxidized, and the feature such as soluble in water.
The sample ore that this experiment adopts is the typical low-grade bauxite in Henan area, and its chemical composition and mineral composition are: Al
2o
356.80, SiO
213.97, A/S is 4.07, belongs to low-grade bauxite.The mineral chief component of ore is diaspore 55.5%, boehmite 1.50%, kaolinite 10.50%, illite 16.00%.
To selected mineral by selective milling make it-0.074mm accounts for 70%-80%, after classification, coarse granule carried out to flotation with synthetic collecting agent, the rough concentrate that its result and selective milling-aggregative flotation technique obtain compares.The alumina silica ratio of the concentrate that its raw granulate fraction obtains through one roughing is 7.30, and collecting agent used is the collecting agent that embodiment 1 makes; And the alumina silica ratio of the rough concentrate directly obtaining by selective milling-aggregative flotation technique is only 5.71.The alumina silica ratio of concentrate relies on more merely the alumina silica ratio of the concentrate that grading obtains to have significant raising.Illustrate that flotation has good effect to this kind of collecting agent for low-grade bauxite coarse granule.
