A method for treating fluorine-containing rare earth mineral particles, comprising the following steps: mixing the first batch of fluorine-containing rare earth mineral particles with the first sulfuric acid solution, and then heating the mixture for liquid-solid reaction, condensing and absorbing steam through a tail gas system, wherein a sulfuric acid concentration of the first sulfuric acid solution is 40-85wt%; wherein the liquid-solid reaction is performed under continuous stirring, the reaction temperature is 120-180°C, and the reaction time is 0.5-2 hours; after the reaction, separating solid phase and liquid phase to obtain acid filtrate and acid residue; leaching the acid residue with water to obtain aqueous leaching liquor of rare earth sulfate and aqueous leaching residue; adding the second sulfuric acid solution to the acid filtrate so that the sulfuric acid concentration of the acid filtrate is 40-85wt%; and then circularly executing the steps - for treating the i th batch of fluorine-containing rare earth mineral particles, wherein the character "i" is a natural number greater than or equal to 2; wherein the first batch of fluorine-containing rare earth mineral particles and the i th batch of fluorine-containing rare earth mineral particles are rare earth mineral particles without performing roasting decomposition; wherein the addition amount of the second sulfuric acid solution is based on the actual consumption of sulfuric acid in the previous round of liquid-solid reaction; characterized in that the first batch of fluorine-containing rare earth mineral particles and the i th batch of fluorine-containing rare earth mineral particles are selected from the group consisting of the bastnaesite from Mianning in Sichuan Province and the mixed rare earth concentrate from Baiyenebo; the weight ratio of the sulfuric acid in the first sulfuric acid solution to the bastnaesite from Mianning in Sichuan Province is 3.4-3.8:1 or the weight ratio of the sulfuric acid in the first sulfuric acid solution to the mixed rare earth concentrate from Baiyenebo is 4-5:1. mixing the first batch of fluorine-containing rare earth mineral particles with the first sulfuric acid solution, and then heating the mixture for liquid-solid reaction, condensing and absorbing steam through a tail gas system, wherein a sulfuric acid concentration of the first sulfuric acid solution is 40-85wt%;
