Study on High Efficient Flotation Recovery of Some Refractory Molybdenum Ore with High Mud Content and Low Grade AITranslate
Abstract AITranslate
The molybdenum content in some molybdenum ore in Fujian is only 0.09%,and most molybdenum exists in molybdenites while a small amount of molybdenum exists in the form of molybdenum oxide ore.The gangue minerals mainly consist of easy-sliming silicate minerals and the flotation activity of the molybdenum ore is low,showing that it is the typical refractory molybdenum ore with high mud content and low grade.A novel surface promoter MCS was introduced to effectively enhance the surface activity of the molybdenum ore,thereby improving the molybdenum flotation recovery.The appropriate grinding fineness,MCS dosage,water glass dosage and collector CM dosage for the flotation were determined through condition experiments.The results show that by using the flotation machine,molybdenum concentrates with a Mo grade of 45.75%and Mo recovery of 82.18%can be obtained after one roughing,three scavenging and seven cleaning,but this process is lengthy and the production and operation costs are high.Through the combined flotation column-flotation machine process,the qualified molybdenum concentrates are gained with a Mo grade of 46.01%and Mo recovery of 87.81%after four cleaning.Therefore,it is re-commended as the principle process for the recovery of molybdenum from the molybdenum ore.
