### Circulating load calculation in mineral processing

2013-1-1 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.

2020-10-23 At some metallic mineral processing plants, material is stored in enclosed bins between processoperations. The emission factors provided in Tables 11.24-1 and 11.24-2 for the handling and transferof material should be applied to the loading of material into storage bins and the transferring ofmaterial from the bin. The emission factor will usually be applied twice to a storage operation: oncefor the loading operation and once for the reclaiming operation. If material is stored at multiple pointsin the plant, the emission factor
