The invention relates to a fluorite ore beneficiation method, and belongs to the technical field of fluorite ore separation processes. The fluorite ore beneficiation method comprises the following steps that roughing is conducted, specifically, raw fluorite ore power is crushed and then ground to the fineness required by beneficiation, sodium carbonate, water glass and a collecting agent are sequentially added into ore pulp, and flotation is conducted by adopting an alkaline medium to obtain roughing concentrate and roughing tailings; concentration is conducted, specifically, the roughing concentrate obtained through roughing is subjected to multiple times of concentration, acid water glass is added into the ore pulp in each concentration process, and flotation is conducted through an acid medium; the collecting agent is added into the ore pulp to conduct scavenging on tailings obtained after first-time concentration, the acid medium is adopted for flotation in scavenging, and scavenged concentrate is returne
