The invention relates to a separation method of fluorite-containing lepidolite concentrate, which comprises the following steps: adding an inhibitor and a collecting agent A into fluorite-containing lepidolite concentrate pulp to carry out roughing operation to obtain fluorite rough concentrate and roughing tailings; an inhibitor is added into the fluorite rough concentrate for concentration operation, and a fluorite concentrate product is obtained; and after the roughing tailings are subjected to size mixing, a collecting agent B is added for recleaning, lepidolite rough concentrate and recleaning tailings are obtained, and the obtained lepidolite rough concentrate is subjected to blank concentration to obtain a lepidolite concentrate product. The inhibitor is caustic starch and sodium hydroxide; the collecting agent A is sulfonated oleic acid, diesel oil and sodium dodecyl benzene sulfonate; and the collecting agent B is dodecylamine and octadecylamine. According to the method, the fluorite lepidolite is fi
