Abstract

See full text

The flotation process is widely used in mineral industry for the separation of minerals from low-grade ore slurry. Several parameters, such as the bubble size distribution and/or amount of solids in the froth and slurry affect the outcome of the flotation process. To be able to monitor these parameters, knowledge of the temporal changes of froth-slurry phase interface as well as froth-air interface is essential. In the present invention, an electrical resistance tomography probe sensor, which is capable of analyzing the properties of froth and slurry based on the correlation between the estimated conductivity information and the parameters of interest, is introduced.
