  • Metallurgical Accounting Formulas Concentration and

    2020-04-20  Ratio of concentration can be thought of as the number of tons of feed required to produce 1 ton of concentrate. The ratio, K, for a separation can be obtained directly from the product weights or from the product assays if the weights are not known: K = F /C = (c — t)/(f-t) = the concentration ratio. At operating plants, it is usually simpler to report the K based on assays.
