Summary: | The invention relates to a micro-fine particle rare earth ore carrier flotation method. The micro-fine particle rare earth ore carrier flotation method is characterized by including the following steps that (1) -5 micron slurry is desorbed from -20 micron micro-fine particle rare earth ore, the micro-fine particle rare earth ore with the size fraction being -20 micron+5 micron is obtained, water is added to conduct size mixing until the concentration ranges from 30% to 40%, an adjusting agent is added, the pH of ore pulp is controlled to range from 8 to 10, and stirring is carried out for 15 min to 20 min; (2) water is added into carrier ore to conduct size mixing until the concentration ranges from 40% to 50%, a collecting agent and an adjusting agent are added, the pH of the ore pulp is controlled to range from 8 to 10, and stirring is carried out for 5 min to 10 min; (3) the above carrier ore for size mixing and the micro-fine particle rare earth ore are mixed according to the mass ratio being 1:4, heating |
