Embodiment 1
[0021] The composite coal preparation flotation agent is composed of 50% of light diesel oil, 0.5% of sodium lauryl sulfate, 0.4% of alkyl glucoside, 3% of alkylphenol polyoxyethylene ether and 46% of water in mass percentage. Sodium lauryl sulfate, alkyl glucoside, and alkylphenol polyoxyethylene ether were respectively configured into aqueous solutions with a mass fraction of 5%, 10%, and 20%, and then 25mL of light diesel oil was added to the reaction vessel, and magnetically Add 5mL sodium lauryl sulfate, 2.5mL alkyl glucoside and 7.5mL alkylphenol polyoxyethylene ether under the condition of stirring. After stirring for 5 minutes, use a high-speed cutting emulsifier to emulsify at a working speed of 3000r / min for 10 minutes to obtain Milky white water-soluble compound coal preparation flotation agent.
[0022] The composite coal preparation flotation agent prepared in this example was left to stand naturally at room temperature for 24 hours, and was shaken and shaken in d...
