The Ways of Selecting Flotation Machine

The type of the flotation machine and the specification selection have something to do with the nature of the raw ores, equipment performance, concentrator scale, the structure of the process and other factors. When choosing the flotation machine, the users  should pay attention to the following problems:

1. The nature of the ore and the requirements of sorting operations: generally, as for the coarse-grained and large ores, it will use the flotation method with high concentrations to reduce the sedimentation rate of mineral particles and to reduce the deposition of the mineral particles. Therefore, it is better to use the high-energy mechanical flotation machine. This flotation machine transfers the slurry fast and the stirring ability is strong and it is also easy to start after the shutdown. In the flotation process of low grade sulphide, low-speed air inflation is more favorable for the sorting effect. The ores that are prone to generate sticky foam should choose the flotation machine with large air inflation in the flotation process. Selection operation is to improve the concentrate grade and the foam layer should be thin to create better conditions for the separation of the gangue. Therefore, the selection of flotation separator in the selection operation should be different from that in the scavenging operation.

2. The slurry flow rate: a reasonable choice of the specifications of the flotation machine should be based on the slurry flow rate. To ensure the sorting effect, it should ensure that the slurry should has some residence time in each flotation tank. Too long or too short will cause the loss of useful minerals. Therefore, the specifications of the flotation machine should comply with the scale of the dressing plant. 

3. To determine specifications and quantity of the flotation machine through the comparison of technical and economic indicators: in the comparison of the programs, the comprehensive comparison of sorting indicators, operating expenses, operating management, maintenance and overhaul should be conducted. The sorting indicators should be the dominant factor. 

4. To pay attention to the availability and manufacturing quality of the equipment and the supply of the spare parts.
