| description | The invention relates to a lepidolite beneficiation method which comprises the following steps: grading lepidolite-containing minerals to obtain coarse-grained ores and fine-grained ores; the fine ore is sequentially subjected to desliming and flotation, and first lepidolite concentrate is obtained; the coarse-grain ore is sorted through a spiral chute, and second lepidolite concentrate is obtained; and the first lepidolite concentrate and the second lepidolite concentrate are combined to obtain the lepidolite concentrate. A collecting agent used in flotation is prepared from, by weight, 15-30 parts of oleic acid n-butyl ester sulfate sodium salt, 5-10 parts of coconut oil amine, 7-15 parts of carboxylic acid, 4-8 parts of C1-C3 alcohol and 2-6 parts of methyl isobutyl carbinol. According to the beneficiation method provided by the invention, the gravity-flotation combined beneficiation process is adopted for minerals, the coarse lepidolite is recovered by using a gravity separation method, and the fine lepid |
