The primary crusher gap had drifted open over the weekend, producing coarser feed. Flotation kinetics slowed.
Statistics provides the tools to quantify those errors and act on signal, not noise. Statistical Methods For Mineral Engineers
Calculate moving range of tails: 0.01 → 0.05. Upper control limit (UCL) = 0.08 + 3σ ≈ 0.13. 8 AM tails = 0.14 → Out of control. The primary crusher gap had drifted open over
The foundation of any mineral project is accurate sampling. Since it is impossible to process an entire ore body at once, engineers use statistical theory—most notably Gy’s Sampling Theory Calculate moving range of tails: 0
Online XRF analyzers produce raw counts for 15 elements. A PLS model predicts Cu, Zn, and Pb grades with an R² > 0.9 using only spectral data, without needing extensive matrix corrections.
