A problem for solving mass balances in mineral processing plants is the calculation of circulating load in closed circuits. A family of possible methods to the resolution of this calculation is the iterative methods, consisting of a finite loop where each iteration the initial solution is refined in order to move closer to the exact solution.

One approach to such calculations uses thermodynamic data and is exemplified by the work of Weill et al. (1979) and Burnham (1979). At present, thermodynamic data and models are insufficient to allow calculation of phase diagrams for many simple systems of geological interest, much less the complex multicomponent systems in which rocks melt …

2-tier approach to mass balance of multi-level mineral processing data: 1 219 cuit data. It is however important to recognize that precisely because the lo- cally balanced data deviate the least from the measured data, the resulting performance indices are likely to be the most reliable that one can obtain from the given measurements.

It is carried out by a Monte-Carlo technique [9], or by a linearization of the mass conservation equations [I0, 3, 1 1, 12], the latter method giving a very good approximation of the former one [7]. The sensitivity analysis is an essential part of a mass balance calculation for a complex mineral processing flowsheet.
