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.

high circulating load ratios, are desirable to make sure mill power is being applied to coarse, not to overgrinding fines. This is demonstrated in early work by E W Davis (shown in Figure1). Figure 1 demonstrates that a high circulating load ratio gives the best circuit production rate of new fines at a given energy input (Davis, 1925).

where R, is the circulating load (in reverse circuit) expressed as percent of new feed, f is the percentage screen undersize material in the new income feed (F tons), and all other symbols have the same nomenclatures as mentioned before. If the new feed is free of screen undersize material, i.e., f = 0. the circulating load (R,,) will be:
