Are you looking for a higher recovery rate in the flotation process by means of automation and instrumentation? A full optimization for a maximum recovery in the flotation process is achievable when a novel of instruments and analyzers get used together. Such as density gauges, level gauges, flow meters, froth cameras, etc.
The froth flotation process
In previous process stages, fine particles got created, and valuable minerals released from their carriers, also called the gangue. In general, flotation is for separation and recover. The valuables are then concentrated and separated from unwanted (gangue) particles.
This is possible by using chemicals and froth. Basically, this process exploits differences in surface properties between minerals and gangues. The froth flotation principle is a complex combination of the laws of surface chemistry, crystallography and physics. The process efficiency depends on aspects such as density, electrical conductivity and physical and chemical properties. Without a flotation process, many metals and inorganic raw materials would be extremely scarce and expensive. There are currently not many high-grade deposits processed by simple physical and mechanical methods.
Purpose of process control
The main objective when controlling the flotation process is to maximize the quality of the throughput. An enriched product is then created by decreasing the amount of gangue. To achieve these objectives the slurry needs to be continuously monitored and controlled. This allows process stabilization and ensuring optimal flotation conditions.
