Embodiment 1
[0025] A kind of waste oil collophosphane reverse flotation collector preparation method steps are as follows:
[0026] 1. Weigh as follows according to the mass ratio: waste oil fatty acid 100g, sodium hydroxide 12g, surfactant OP‐107g, water 74g.
[0027] 2. Add 12g parts of sodium hydroxide to 32g water to prepare sodium hydroxide solution.
[0028] 3. Add the sodium hydroxide solution to 100 g of waste oil fatty acid, heat to 90° C., and stir for 20 minutes to saponify the fatty acid and the sodium hydroxide solution to obtain a mixture of fatty acid soap and incompletely reacted fatty acid.
[0029] 4. Add 7g of surfactant OP‐10 to 42g of water, heat to 70°C and disperse evenly.
[0030] 5. Add the uniformly dispersed surfactant OP-10 solution to the mixture of fatty acid soap and incompletely reacted fatty acid, stir at 90°C for 20 minutes, and obtain the reverse flotation collector 1 after the emulsification is complete.
Embodiment 2
[0032] A kind of waste oil collophosphane reverse flotation collector preparation method steps are as follows:

Abstract
The invention relates to a swill-cooked dirty oil collophanite reverse flotation collecting agent and a preparing method thereof. The collecting agent comprises, by mass, 90-100 parts of swill-cooked dirty oil fatty acid, 10-20 parts of sodium hydroxide, 5-15 parts of OP-10 and 60-80 parts of water. The preparing method of the collecting agent includes the steps that a sodium hydroxide solution is added into the swill-cooked dirty oil fatty acid for saponification, and a mixture of fatty acid soap and incomplete reaction fatty acid is obtained; water is added to a surface active agent, and the surface active agent with the water is heated and evenly scattered to be added into the mixture of the fatty acid soap and the incomplete reaction fatty acid according to different proportions, sufficient heating is carried out for even stirring, and the reverse flotation collecting agent is obtained after emulsification is complete; the solubleness and the dispersity of the collecting agent in water are good, the selectivity is good, the collecting capacity is high, the preparing process is simple and rapid, carbonate minerals can be effectively removed at a normal temperature, the phosphorus concentrate grade is improved, and efficient normal temperature reverse flotation of collophanite is achieved.
Description
technical field [0001] The invention belongs to phosphate rock flotation technology, and in particular relates to a reverse flotation collector of waste oil collophosphate and a preparation method thereof. Background technique [0002] The flotation performance of collophosite flotation agents, especially collectors, is an important factor for the quality of collophosite flotation indicators. Collophosite flotation mainly uses collectors such as oleic acid, tall oil and oxidized paraffin soap, or collectors compounded with them as raw materials. At present, oleic acid fatty acid collectors and their compound products are widely used, for example, compound collectors made of soybean oil, rapeseed oil, cotton oil, etc. In terms of compounding technology, the main development trends in recent years are multifunctionalization, heteropolarization, non-ionization and mixed synergistic drugs. [0003] Although there have been many advances in the development of pharmaceutical syn...
