Statistical Methods For Mineral Engineers Here
Statistical Methods For Mineral Engineers " is most notably the title of a widely used monograph by Emeritus Professor Tim Napier-Munn , published by the Julius Kruttschnitt Mineral Research Centre (JKMRC) Core Purpose and Scope The text is designed as a practical guide for metallurgists and plant engineers
Practical output: A reconciled feed grade that is statistically more reliable than any single direct measurement. Statistical Methods For Mineral Engineers
Case Example: Improving Rougher Scavenger Recovery
Scenario: A lead-zinc plant sees erratic recovery (70–85%). Statistical Methods For Mineral Engineers " is most
Strengths and Weaknesses
$$ \gamma(h) = \frac12N(h) \sum_i=1^N(h) [Z(x_i) - Z(x_i + h)]^2 $$ Null Hypothesis (H₀): Mean Monday recovery = Mean
- Null Hypothesis (H₀): Mean Monday recovery = Mean weekly recovery.
- Data: Monday shift (n=5 assays): 88.1, 87.6, 88.9, 87.3, 88.4 → Mean = 88.06%
Other shifts (n=20 assays): Mean = 91.8%, σ = 1.5%
