Technical field
The preparation method of the collecting agent that a kind of bauxite direct-flotation desiliconisation is used, particularly a kind of production method of bauxite flotation collecting agent intermediate products hydroximic acid salt.
Background technology
Mineral dressing and silicon removal of bauxite is that an effective way has been found in China's middle-low bauxite reasonable resources utilization.The commercial application of bauxite forward flotation technology in the Liquor of Ore Dressing Bayer process alumina producing improves the utilization rate of China's bauxite resource effectively, thereby improves the market competitiveness of China's aluminum oxide industry.
Collecting agent is the most critical technology that mineral floating separates, and the synthetic the most effectively collecting agent of exploitation is the important channel of improving floatation process and economic indicator.The collecting agent that oxide ore flotation adopts mainly is oxidized paraffin wax soap, tall oil, oleic acid, hydroximic acid etc. or their mixture.At present; In bauxite forward flotation technology; Generally select the KL collecting agent for use, will use the raw material hydroxylamine hydrochloride in product hydroximic acid salt synthetic therebetween, the chloride shift in the final hydroxylamine hydrochloride has been arrived in the collecting agent; Chloride ion content in the collecting agent reaches 1.27g/L; Calculate by every month collector dosage of 2500 tons, the chlorion of bringing in the Liquor of Ore Dressing Bayer process alumina producing flow process in every month has reached 3.175 tons, and the stainless steel equipment in the flow that exists of these chlorions possibly cause corrosion to a certain degree.
Summary of the invention
The object of the invention is exactly the deficiency that exists to above-mentioned prior art, provides a kind of and can reduce effectively that chlorion, the collecting ability brought in the alumina producing flow process are strong, consumption is few, the bauxite flotation of good separation effect is with the preparation method of collecting agent.
The objective of the invention is to realize through following technical scheme.
A kind of bauxite flotation is with the preparation method of collecting agent; It is characterized in that its process is to use soda bath, HAS solution and methyl benzoate to be raw material; Behind the hydroxyl oximation reaction, obtain containing the mixed solution of benzene first hydroximic acid sodium, sodium sulphate, first alcohol and water, again with the mixed solution dilute with water that makes.
A kind of bauxite flotation of the present invention is characterized in that using the mole proportioning of soda bath, HAS solution and methyl benzoate to be 2:1.2:1 with the preparation method of collecting agent.
A kind of bauxite flotation of the present invention is characterized in that with the preparation method of collecting agent hydroxyl oximation reaction temperature is 50 ~ 60 ℃, and the time is 6-8 hour.
A kind of bauxite flotation of the present invention is characterized in that with the preparation method of collecting agent the mixed solution that makes is that the dilution ratio of mixed solution and water is 1:4 during dilution with softening water-reducible.
A kind of bauxite flotation of the present invention is characterized in that in hydroxyl oximation reaction process, adopting cooling water temperature with the preparation method of collecting agent.
Adopt the collecting ability of the KL collecting agent that method of the present invention makes strong, consumption is few, good separation effect, effectively reduces and brings the chlorion in the alumina producing flow process into, reduces the corrosion to stainless steel equipment in ore dressing and the alumina producing flow process.
The specific embodiment
A kind of bauxite flotation is with the preparation method of collecting agent; Is that the 2:1.2:1 adding is equipped with in the agitated reactor of cooling water temperature device with soda bath, HAS solution and methyl benzoate by proportioning; Under 50 ~ 60 ℃ of temperature, carried out the hydroxyl oximation reaction 6-8 hour; Obtain containing the mixed solution of benzene first hydroximic acid sodium, sodium sulphate, first alcohol and water; Then mixed solution is delivered in the thinning tank, the dilution ratio 1:4 adding demineralized water by mixed solution and water stirs in thinning tank simultaneously, will obtain solution and send into storage tank.
Below in conjunction with instance the present invention is described further.
