  • This study investigated the mineralogical characteristics and basic flotation properties of domestic molybdenum ores. The source mineral of molybdenum was identified as molybdenite, and the main gangue minerals in the raw ore were silicate minerals. Copper, lead, and zinc were also found in trace amounts. Based on the results of basic flotation properties, molybdenite's zeta potential showed negative charges in all pH ranges. The contact angle of molybdenite increased with pH, reaching a maximum of 74° at pH 9. In optimal conditions, the grade and recovery of the concentrate by unit flotation were MoS2 82.4% and 92.04%, respectively. Further investigation of the impurities in the concentrate revealed a sulfide mineral with surface characteristics similar to molybdenite and silicate minerals combined with molybdenite, which may degrade the quality of the concentrate. To improve the concentrate quality, we intend to control silicate minerals through regrinding and liberation and use column flotation to improve fine particle separation efficiency.
