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% This means that 4.3% of the copper present in the ore was lost in the tailings.
