| titleOfInvention | Preparation method and application of rare earth ore flotation collector |
| abstract | The invention provides a preparation method and application of a rare earth ore flotation collector, and belongs to the technical field of ore dressing. The preparation method comprises the following steps: (1) the method comprises the following steps of (1) mixing illegal cooking oil, methanol and concentrated sulfuric acid in a mass ratio: methanol: 1.0-1.2% of concentrated sulfuric acid: 1.1-1.8: 0.05-0.09, stirring and reacting for 5-12 hours at the temperature of 60-90 ℃ to obtain a product 1; (2) the preparation method comprises the following steps of (1) mixing hydroxylamine hydrochloride, water and sodium hydroxide according to the mass ratio: water: 1.0 to 1.3% of sodium hydroxide: 6.4-9.3: 1.9-2.4, stirring and reacting for 1-3 hours at 20-30 ℃ to obtain a product 2; (3) and (3) mixing the product 1 with the product 1: and (3) the product 2 is 1.0-1.2: and (3) adding 0.28-0.48 of the obtained product into the product 2, and stirring and reacting for 4-6 hours at the temperature of 40-60 ℃ to obtain the collecting agent. The invention relates to a rare earth ore efficient flotation collector, which solves the problems of complex production process flow and unsatisfactory rare earth ore concentrate grade and recovery rate indexes caused by high cost, poor selectivity and difficult operation in production of the conventional flotation collector. |
