Circulation Load vs Fresh Feed with Example - Minerallurgy

2021-2-26 · From the above example, we can determine the simple balance. 700=0.65*700 + 0.35*700=385+315. The 385 tons underflow will be recycled. 315 tons is the overflow will be taken for the further operations. Therefore 315 tons per hour is the fresh feed. The circulating load ratio is equal to 385 upon 315, so that is equal to 1.22.
