Problems solved by technology

The collectors used in the flotation of medium and low-grade phosphate rock at home and abroad are mainly fatty acids and their soap collectors. The fatty acid collectors are characterized by strong collection performance, but they also have poor selectivity and poor water solubility at room temperature. , Need heating flotation, large dosage of chemicals, high cost of beneficiation, etc.

Embodiment 1

[0010] 1) Weigh 13.7 parts by weight of fusel oil and 22 parts by weight of citric acid and place them in Reactor 1, control the reaction temperature at 40°C, and stir for 2 hours at a constant temperature of 400r / min, then add 5.58 parts by weight of cotton Oil fatty acid soap, continue heating and stirring reaction at this temperature and rotating speed for 2h. After standing for reaction for 12 hours, add 1.56 parts by weight of sodium carbonate (or sodium hydroxide) and 0.68 parts by weight of sodium oleate aqueous solution to adjust the pH = 8.5, place it under the same conditions as above for magnetic stirring for 2 hours, and set aside.

[0011] 2) Add 20 parts by weight of polyethylene glycol and 15 parts by weight of sodium silicate solution with a mass fraction of 10% into the reaction kettle 2, and stir for 1 h at room temperature. Take 60 parts by weight of the solution prepared in step 1) and place it in the reactor 2, heat it in a water bath at 50°C for 30 minute...

Embodiment 2

[0013] It is exactly the same as Example 1, except that 23 parts by weight of citric acid, 5.68 parts by weight of cotton oil fatty acid soap and 3.78 parts by weight of phenoxyacetic acid composite product are added.

Embodiment 3

[0015] It is exactly the same as Example 1, except that 24 parts by weight of citric acid, 5.78 parts by weight of cotton oil fatty acid soap and 3.88 parts by weight of phenoxyacetic acid composite product are added.

Abstract

The invention discloses a preparation method of a novel flotation collector. The preparation method comprises the steps that cotton oil fatty acid is taken as a raw material and then subjected to saponification treatment to obtain cotton oil fatty acid soap, citric acid, sodium silicate, sodium carbonate, sodium oleate and phenoxyacetic acid composite products are added, and composite fatty acid citrate-based carboxylic acid containing multi-element carboxyl is obtained and applied to phosphate ore flotation by serving as a phosphate ore collector. The synthetic agent has the characteristics of being good in water solubility, high in collecting capability, good in selectivity and good in low temperature resistance, has the advantages of being low in agent dosage and production cost compared with unmodified fatty acid, and has the important significance for reducing the flotation cost and improving the flotation efficiency.

Description

technical field [0001] The invention relates to the preparation of a novel flotation collector, in particular to a novel flotation collector for phosphate rock flotation. Background technique [0002] Phosphate rock is a very important chemical mineral raw material. Phosphorus products are widely used in various industries such as agriculture, food, textile, medicine, printing and dyeing, and national defense. Its importance is self-evident. The characteristic of my country's phosphate rock resources is that although the total reserves are abundant, most of them are medium and low-grade phosphate rocks with low phosphorus content. Except for a few rich ores that can be directly used in production, most of the phosphate rocks need to be sorted to remove impurities and enrich. Can be applied. However, my country's phosphate rock has a long history of mining, and problems such as "mining the rich and abandoning the poor" and "low recovery rate" caused by irregularities in the i...
