Predicting collapse of the solid content in a column flotation cell using tomographic imaging technique

摘要

We present a new approach for predicting the collapse of solid content in the froth bed of a column flotation cell. We consider a laboratory size column flotation cell which is imaged using three-dimensional electrical resistance tomography. The results show that tomographic images yield estimates for the time-dependent ore and air distributions in the flotation cell which can be utilized in predicting the behaviour of the flotation process. The first laboratory results indicate that the prediction of the collapse of the solid content in froth bed could be possible using tomographic imaging.
