A method is described to predict the content of a desired element in the products of a beneficiation process as a function of the impurities in the raw material. The method shows one of the possibilities of utilizing factor analysis and regression analysis for routine industrial purposes. The method consists of (a) developing an on-line multielement analysis, (b) finding the elemental and mineralogical relationships in the product, by factor analysis, (c) determining the independent variables, (d) finding the relationships between the concentrations of the impurity variables in the raw material and in the product, (e) and developing a linear model to predict the desired element’s content. The predictions can be used for mining and plant control. Examples from a phosphate beneficiation by calcination process are given.
