iron concentrate ore milling recovery

Concentration and Recovery Formulas. These are used to compute the production of concentrate in a mill or in a particular circuit. The formulas are based on assays of samples, and the results of the calculations are generally accurate— as accurate as the sampling, assaying, and crude ore (or other) tonnage on which they depend.

R = 100 c/Kf = recovery % By weights F and C, plus assays c and t; R = 100 Cc / (Cc+t(F—C)) = recovery % A copper concentrator is milling 15,000 tons/day of a chalcopyrite ore assaying 1.15% copper. The concentrate and tailings produced average 32.7% and 0.18% copper, respectively. I let you do the math! Three product (bi-metallic) formulas
