Embodiment 1
[0028] A preparation method of gasification slag flotation collector, comprising the following steps:
[0029] S1. Add deionized water to sodium lauryl sulfate at a mass ratio of 1:1, heat to 50°C with a magnetic stirrer and stir for 10 minutes to prepare sodium lauryl sulfate solution;
[0030] S2. Add non-polar hydrocarbon oil into the sodium lauryl sulfate solution at a mass ratio of 1:9, heat to 70° C. with a magnetic stirrer and stir for 10 minutes to obtain a mixed solution;
[0031] S3, adding ultra-fine graphite particles into the S2 mixed solution at a mass ratio of 120:1, using an ultrasonic oscillator to oscillate and mix for 3 minutes to obtain a graphite mixed solution; the diameter of the ultra-fine graphite particles is 1-2 μm;
[0032] S4. Add an emulsifier to the graphite mixed solution obtained in S3 at a mass ratio of 20:1, heat to 70° C. with a magnetic stirrer and stir for 1 min to obtain a gasification slag flotation collector.
[0033] Above-mentioned e...
Embodiment 2
[0035] Carry out gasification slag flotation test using a kind of gasification slag flotation collector provided by the invention
[0036] 1. prepare collector, process is as follows:
[0037] S1. Add 1 g of sodium lauryl sulfate to 1 g of deionized water, heat sodium lauryl sulfate and deionized water to 50°C with a magnetic stirrer and stir for 10 minutes at the same time to obtain a sodium lauryl sulfate solution;
[0038] S2. Add 18 g of diesel oil to the product of S1, and heat it to 70°C with a magnetic stirrer while stirring for 10 min to obtain a mixed solution;
[0039] S3, adding 0.17g ultrafine graphite to the S2 product, using an ultrasonic oscillator to vibrate and mix for 3 minutes to obtain a graphite mixed solution;
[0040] S4. Add 1 g of polyethylene glycol to the product of S3, heat to 70° C. with a magnetic stirrer and stir for 1 min to obtain a gasification slag flotation collector.
[0041] 2. Test group flotation
[0042] Grind the gasification slag f...
Embodiment 3
[0051] Adopt the same material and method as embodiment 2, adjust the diesel oil in the collector to be kerosene, record the flotation contrast test result as shown in table 2 below:
[0052] Table 2 flotation comparison test results
[0053]
[0054] Data comparison shows that using kerosene to prepare collectors, compared with directly using kerosene, the concentrate flotation yield has a greater degree of increase, an increase of 11.40%, showing that the collector prepared by the present invention has a better effect.
