The invention provides a method for preparing a coal dressing collecting agent by using illegal cooking oil and belongs to a preparation method of a flotation agent. The method is mainly used for solving the problems of daily waste oil treatment and coal flotation. The method comprises the following steps: (1) firstly heating the illegal cooking oil or swill to 50-80 DEG C, stirring and filtering, thus obtaining crude oil; (2) heating the crude oil to 60-90 DEG C, and carrying out hydrolysis saponification reaction on the crude oil for 1-2 hours, thus obtaining emulsion; (3) adding a saturated salt solution to soap while stirring, carrying out the addition of the saturated salt solution twice, and standing still for precipitation, so as to obtain a soap base; and (4) adding the soap base to a reaction kettle in which argon gas is fed and a catalyst is contained, and reacting for 1-3 hours at the temperature of 180-240 DEG C, thus obtaining colorless liquid, namely the coal dressing collecting agent. The method has the advantages that the originally discarded illegal cooking oil turns into wealth and is prevented from being reused for cooking, environments are protected, the product cost is greatly reduced, and the economic and social benefits are very remarkable.
