1. Introduction. Rocks, ores, and their subproducts have always been of great importance for civilization. For example, as mentioned in De Re Metallica—one of the oldest known book about mineral processing—back in the Medieval Age, male slaves and peasants, the 'breakage section', swung heavy mallets and hammers to break rocks to …

design material balance; operating plant material balance. The design material balance is typically faced during plant design when the flotation test work results and a flowsheet diagram are the only known values. Design material balance purpose is to find values for the unknown flow parameters.

One way of processing those data is regression analysis, which supplies lengthy equations to minimize the errors in reproducing the data base [e.g., Weill et al. (1979) and Hostetler and Drake (1978)]. A similar method of estimating liquidus temperatures using linear equations is that of Roeder (1975), based on the suggestion of French (1971).
