Problems solved by technology

Chinese patent application CN102179311A discloses a kind of waste oil to prepare anion collector, use waste oil for ore flotation, greatly reduce the raw material cost of anion collector, but the composition of waste oil is complicated, impurity content is high, so the waste oil The oil saponification process is complicated, and the collectors obtained are not satisfactory in terms of selectivity and recovery
Sodium petroleum sulfonate is a by-product produced in the oil refining process of the petrochemical industry. There is a large backlog of this product due to the lack of effective utilization methods, resulting in waste of resources and environmental pollution.
Chinese patent application CN103920596A discloses a collophosite combined flotation collector, which uses sodium petroleum sulfonate, oleic acid soap, and fatty acid polyol ester as raw materials to prepare the collector, but the collector needs to be made of high-purity oil Acid soap is used as the main raw material, and the product cost is high, so it is not suitable for the application of phosphorus tailings
Although waste oil and sodium petroleum sulfonate have been used separately as raw materials for collectors in the prior art, both of them are waste by-products with many impurities, complex components, and large differences in specific gravity. There is incompatibility when the substances are mixed, and the respective effects are offset and the harvesting effect is reduced, so they cannot be used together as raw materials for collectors

Embodiment 1

[0023] This example relates to the anion collector of the present invention and its preparation.

[0024] The preparation method is as follows: Add the raw materials according to the established order, first stir the waste oil and heat up to 35-38°C, then add sodium petroleum sulfonate, continue to stir and heat up to 55-58°C, then add triethanolamine and phthalic acid di Methyl ester, keep stirring, control the temperature not to exceed 60°C, after all raw materials are fully fused into a uniform solution, add an aqueous solution with a temperature of 40±1°C and a pH value of 10, heat while stirring, control the temperature at 65°C-80 Carry out saponification reaction at ℃ for 20-30 minutes, wait until the material is translucent, then add surfactant fatty alcohol polyoxyethylene ether sodium sulfate (AES) or α-sulfo fatty acid methyl ester sodium salt (MES), and then After stirring for another 10 minutes until uniform, adjust the pH to 7.5±0.1 and lower to room temperature t...

Embodiment 2

[0029] This example relates to the performance evaluation of the anion collector of the present invention.

[0030] The anion collector of Example 1 is used to carry out flotation to the phosphorus-containing tailings obtained after iron flotation of phosphorite ore, and the flotation operation steps are as follows:

[0031] (1) Take the slurry from the phosphorite tailings after flotation in a mining site, divide it into several parts after wet mixing, and test its phosphorus grade;

[0032] (2) Using a 1.5L flotation machine in the laboratory, the roughing and sweeping impeller speeds are adjusted to 2000 rpm, and the selected impeller speeds are adjusted to 1500 rpm;

[0033] (3) According to figure 1 The shown test procedure and sequential dosing form a closed-circuit test procedure; the roughing and sweeping flotation time is 3 minutes, the refining 1 flotation time is 2 minutes, and the refining 2 and refining 3 flotation time are both 1.5 minutes;

[0034](4) The conc...

Embodiment 3

[0040] This embodiment relates to the performance comparison between the anion collector described in the present invention and the existing anion collector.

[0041] The anion collector of the present invention and the existing anion collector are used in the same flotation experiment, and the phosphorus-containing tailings obtained after iron flotation are carried out to flotation, and the flotation process is the same as Embodiment two, flotation result is:

[0042]

[0043] As can be seen from the results in the table above, the anion collector of the present invention is used for flotation of phosphorus-containing tailings obtained after iron flotation of ferrophosphorite, which can improve the phosphorus collection rate, improve the concentrate grade obtained, and make After the phosphorus tailings are floated by the anion collector of the present invention, the residual phosphorus grade is reduced to extremely low, and the phosphorus in the tailings can be eff...

Abstract

The invention provides an anionic collector. The anionic collector is mainly prepared from, by weight, 25-30 parts of petroleum sodium sulfonate, 20-25 parts of drainage oil, 2-3 parts of triethanolamine, 3-4 parts of dimethyl phthalate, and 35-40 parts of water with the pH value being 10. According to the obtained anionic collector, the two low-cost waste by-products, namely petroleum sodium sulfonate and drainage oil, are used as the main raw materials, so that the cost of the anionic collector is greatly reduced, the phosphorus collection rate is increased, the grade of phosphorus remaining after phosphorus tailings are subjected to floatation through the anionic collector is lowered to an extremely low level, and phosphorus in the tailings is efficiently recovered. According to a preparation method provided by the invention, the raw materials do not need to be separated and purified, reaction products are all used as anionic collectors, no waste is produced, the reaction temperature requirement is low, waste resources are effectively utilized, huge economic benefits can be created, and the anionic collector is applicable to large-scale industrial application.

Description

technical field [0001] The invention relates to the technical field of flotation ore, in particular to an anion collector and a preparation method of the anion collector. Background technique [0002] The mining of ore mainly adopts the flotation process, which uses the difference in wettability of the mineral surface to separate the minerals. In the flotation process, flotation agents are usually used to change the physical and chemical properties of the mineral surface or create conditions to adjust the floatability of the minerals. According to the mechanism of action, flotation reagents can be divided into three categories, namely collectors, foaming agents and regulators. Among them, collectors determine the buoyancy of minerals, so they play a pivotal role in the flotation process. According to the molecular structure, collectors can be divided into polar collectors and non-polar collectors, among which polar collectors can be divided into ionic and non-ionic according...
