Transparent calculation
Q = feed (t/h); U = separation effort (%); H = hardness factor; G = feed grade (% Cu).
R = clip(94 − 0.000025(Q−750)² − 0.0025(U−72)² − 4(H−1), 0, 100)
P = Q × (6 + 0.08U) × H
Cu = Q × G/100 × R/100
Contribution = Cu × Cu value − P × power cost − Q × variable costRead the result correctly
Coefficients are invented for this demonstration. Copper value is a scenario input, not a current market quote. Contribution excludes capital, fixed costs, payability, treatment charges and other site-specific effects.
Search grid: 5 t/h feed × 1 percentage-point effort. The result is the best feasible grid point, not a continuous or dynamic plant optimum. Energy minimisation can favour low production; compare contribution before deciding.
Sensitivity varies grade ±10% and recovery ±2 percentage points at fixed setpoints. It is not a confidence interval. Annualisation assumes unchanged conditions and hours.
From demonstration to deployment: calibrate against historian data, validate on withheld periods, review safe limits with operations, and verify benefits through a controlled trial. Discuss your circuit ↗
