Embodiment 1
[0018] The first step: prepare the mixed material. Weigh 60% of the materials oleic acid, 30% of stearic acid, and 10% of C5-C9 fatty acids in proportion, respectively add them to the reaction kettle 1, heat and stir to 100° C., and keep at constant temperature for 1 hour to make a mixed material;
[0019] The second step: heating saponification. Weigh a certain amount of the above mixed material and add it to the reaction kettle 2, then add 56.5% water and 6% solid sodium hydroxide in proportion, heat and stir to 95°C, and react at constant temperature for 1 hour;
[0020] The third step: the compounding of mixed fatty acid and surfactant. Add 5% terpineol, 5% polyoxyethylene laurate sulfonate, 1.5% TX emulsifier and 2% sodium carbonate to the reaction kettle 2, stir for 40 minutes at a constant temperature of 95°C, and pack it out of the pot That's it.
[0021] The agent has been successfully used in mineral processing production, such as in the flotation production of ph...

Abstract
The invention discloses a formula and a preparation method of a phosphorite reverse flotation deoxidization magnesium collecting agent which is simple in process and favorable in using effect. In a process of preparing a mixed material, the input ratios of the materials are as follows: the input ratio of oleic acid is 50-60%, the input ratio of stearic acid is 40-30%, and the input ratio of C5-C9 fatty acid is 10%; the input ratios of the materials in a process of heating and saponifying are as follows: the input ratio of the mixed material is 37.5%, the input ratio of water is 56.5% and the input ratio of solid natrium hyelroxide is 6%; in a compounding process of mixing fatty acid and a surfactant, the input ratios of the materials are as follows: the input ratio of the mixed material is 86.5-90.5%, the input ratio of terpilenol is 3-5%, the input ratio of lauric acid polyoxyethylene ether sulfonate is 3-5%, the input ratio of a TX emulgator is 1.5%, and the input ratio of sodium carbonate is 2%. The method is high in synthesis efficiency, low in equipment requirement, free of pollution and free of emission; the method serves as a clean, environment-friendly and efficient production process; the prepared product is high in water solubility, high in mobility, excellent in dispersion effect and stable and reliable in performance, can be simultaneously adaptive to high-concentration and fine-fraction flotation; the phosphorite reverse flotation deoxidization magnesium collecting agent serves as a beneficiation reagent with high competitiveness and good application prospect.
Description
technical field [0001] The invention relates to a collector formula, in particular to a formula and a preparation method of a magnesium collector for reverse flotation deoxidation of phosphate rock with simple process and good application effect. Background technique [0002] Facing the increasing scarcity of global phosphate rock resources, the effective use of poor, fine, impurity, and refractory phosphate rock has become the main task of mineral processing technology workers. [0003] Because fine-grained ore particles (slime) have the characteristics of small mass and large specific surface area, a series of special behaviors will appear in the fine particles during the slurry mixing and flotation process: First, mutual coagulation between different mineral particles is easy to occur However, non-selective aggregation is formed, and the particles are easy to adhere to the surface of the coarse particles to form a mud cover; secondly, the particles have a large specific s...
