The invention discloses a beneficiation method of hydroxysilicon strontium ore. The technical scheme of the invention adopts a crushing-flotation process, the gangue is inhibited by adding an inhibitor, the strontium ore is activated by a high-efficiency activator, and the cesium is recovered by flotation using a collector . By adopting the technical processing of the silicon containing beryllium beryllium quarry 0.17%, obtained of the metal beryllium ore containing 3.21% beryllium, beryllium oxide, i.e., 8.92%, 85.18% recovery rate, it is possible to achieve high-quality raw material requirements beryllium ore smelting, is The comprehensive utilization of resources provides a new and efficient way. Compared with the current sulfuric acid extraction process, it has the advantages of simple process, good effect and no pollution.
