Sulfide Mineral Flotation Beneficiation Methods And Flow
A complete processing plant consists of four systems:
1. Crushing system: 0-300mm material is stably and evenly fed from the feeder to the primary jaw crusher and crushed into a size of about 0-80mm. Then send it to the fine jaw crusher to crush the particles below 25mm again. The particles of +25mm are first conveyed to the vibrating screen for screening and then to the ball mill grinding system.
2. Grinding system: 0-25mm materials enter a storage bin before entering the ball mill. Enough 0-25mm materials are in the storage bin, and the crushing system can work separately from the grinding system. Then the 0-25mm material is sent into the ball mill through the swing feeder or the electromagnetic vibrating feeder through the belt conveyor. It needs to work together with the spiral classifier. The output from the overflow port of the classifier reaches 200 mesh, the bottom flow coarse particles are returned to the ball mill for grinding, and the circuit is closed. (The smaller the feed particle size of the ball mill, the better, and the grinding efficiency will be much higher.)
3. Flotation system: The 200-mesh material is first pumped from the slurry to the mixing tank to ensure that the material is thoroughly mixed. Add different agents in the flotation machine to separate other minerals. The flotation process has a three-stage flotation separation, which is to maximize the mineral grade.
4. Concentrate filtration system: After obtaining mineral concentrates from the flotation system for high-grade minerals. Concentrate using a thickener to make it denser. It is then sent to a disc vacuum filter to filter the water for more dry concentrated minerals. Then be dried in the sun or dried in a tumble dryer to obtain mineral concentrate.
The sulfide ore flotation plant is a concentrator that efficiently recovers sulfide ore. According to rock and mineral conditions, flow and capacity can be customized as small, medium and large according to requirements. It is generally used for processing sulfide rock gold, copper, silver, zinc, lead, fluorite and other ores; high recovery rate for sulfide minerals. According to the material situation, it can usually rut at 85-90%.
