The invention discloses a lepidolite ore recovery method. The recovery method comprises the following steps: S1, adding a lepidolite ore raw material into a ball mill for ball milling; s2, the raw materials subjected to ball milling in the step S1 are screened for the first time, the aperture of a screen mesh in the first-time screening is 0.8 mm, and screened powder and unscreened powder are obtained; s3, removing iron from the sieved powder obtained in the step S2 through weak magnetism, and recovering magnetic substances through strong magnetism to obtain non-magnetic substances and magnetic substances; the process is simplified, and the operation cost is reduced. The technology of re-grinding and re-separation after grading of the iron lepidolite concentrate better meets the requirement of smelting for the fineness of iron lepidolite, lithium resources are efficiently recycled, and comprehensive benefits are increased. 本发明公开了一种铁锂云母矿回收方法，所述回收方法包括以下步骤：S1、将铁铁锂云母矿原料加入球磨机进行球磨；S2、将经过步骤S1球磨后的原料进行第一次筛分，第一次筛分筛网孔径为
