The calculation using assays alone is % Cu Recovery = 100(20/2 09)(2 09 – 0 1)/(20 – 0 1) = 95 7% This means that 95 7% of the copper present in the ore was recovered in the concentrate while the rest was lost in the tailings (c) The % Cu Loss can be calculated by subtracting the % Cu Recovery from % Cu Loss = 100 – 95 7 = 4 3%
