A blockflow diagram of a typical CIP plant for a nonrefractory gold ore is shown in Figure 2. Table I and Table II illustrate the capital and operating cost breakdowns for a typical South African gold plant. These figures are not a standard but reflect the nature of the ore and the design basis for a particular situation.
1 Froth Flotation – Fundamental Principles
the concentrate. One limitation with this calculation is that it uses the weights of the feed and concentrate. While this data is available in laboratory experiments, in the plant it is likely that the ore is not weighed and only assays will be available. However, it is possible to express the ratio of concentration in terms of ore assays.

Common Basic Formulas for Mineral Processing Calculations
· 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.
