Flotation tests were carried out for a fluorite-calcite symbiosis ore containing 31.09% CaF2 and 53.23% CaCO3, with the predominately valuable mineral of fluorite, and the dominantly gangue minerals of calcite, quartz and feldspar. After being milled to a fineness of -0.074 mm 75%, the ore was processed with acidized sodium silicate and EM-318 as depressants and EM-OL-3 as collector. Adopting a close-circuit flowsheet consisting of two stages of roughing, one stage of scavenging and eight stages of cleaning, a fluorite concentrate grading 97.26% CaF2 at 86.55% recovery can be obtained. Qualified as an acid-grade fluorite powder (with grade FC-97A) according to the Industry Standard for Ferrous Metallurgy (YB/T 5217—2005 (Fluorspar)), this fluorite concentrate can be used as the raw material in high-end fluorine chemical industry.
