摘要：

This paper reports new results regarding the usefulness of colour measurements in flotation process. Colour measurements coming simultaneously from RGB-camera and a spectrophotometer (and from the same measurement point) are compared. The measured variables are used to construct a partial least squares (PLS) model and a multilinear regression (MLR) model for the prediction of the zinc content in the froth. The study shows that both the RGB-camera and spectrophotometer are able to make reliable prediction and makes comparisons between the two modelling techniques.
