A process for the controlled bubble flotation of fine particle zinc oxide ores
ActiveCN116899742Bavoid repeated loopsImprove the flotation processSolid separationMining engineeringFOAM CONTROL
This invention relates to a controlled-foam flotation method for fine-grained zinc oxide ore, belonging to the field of mineral processing technology. Addressing the problems of deteriorating separation indices due to slime recycling, large and poorly fluid foam, stable and highly viscous foam layers, and poor flotation performance in the flotation process of fine-grained zinc oxide ore, this invention improves the flotation process and recovery indices by innovating the flotation process and developing novel flotation reagents. Specifically, it employs a fine scavenging operation to process middlings separately, avoiding their return to roughing and cleaning operations, thus preventing repeated recycling of slime in these operations and directly producing zinc concentrate. Furthermore, it uses a foam control agent to regulate the flotation foam of fine-grained zinc oxide ore, thereby increasing its ore-carrying capacity and improving the stability, viscosity, and fluidity of the foam layer. This facilitates the smooth flotation process of fine-grained zinc oxide ore, achieving higher flotation indices and promoting the efficient recovery of complex and difficult-to-process zinc ore resources.
