Plot cumulative grade on a log-normal probability axis. A straight line indicates single-population log-normality. An inflection point indicates a mixture of two ore types (e.g., high-grade vein material vs. low-grade matrix).
When predicting whether a concentrate will be "on-spec" (>30% Cu) or "off-spec", use logistic regression. The logit link function maps any linear predictor to a probability between 0 and 1.
Modern mineral engineering is increasingly a data-driven discipline. are no longer just tools for publishing research papers; they are operational necessities for optimizing recovery, reducing energy consumption, and predicting plant failure. This article provides a comprehensive guide to the statistical toolkit every mineral engineer—from metallurgist to mine planner—must master. Statistical Methods For Mineral Engineers
“For the last six hours,” she said, pointing to a string of seven points all below the centerline, “we have been running fine. But this run of seven points all below the mean? That’s a Nelson Rule violation. It’s not out of control statistically, but the probability of this happening by chance is less than 1%. It’s a trend. The mill is grinding finer because the new media supplier’s ball hardness is different. We need to back off the feed rate now—not in two hours.”
Mineral engineers don't just process ore; they get it from mines. Geostatistics bridges the gap. Plot cumulative grade on a log-normal probability axis
The average was just a ghost. The plant was either choking or starving, never steady.

Introduction to Statistical Methods to Assess Geological Data
Mineral engineering involves the extraction, processing, and management of mineral resources, including metals, minerals, and energy resources. The field is characterized by complex geological systems, variability in ore quality, and uncertainty in resource estimation. Statistical methods provide a powerful framework for analyzing data, modeling complex systems, and making informed decisions.
Elara was the site’s mineral processing engineer, but her secret weapon wasn't a froth flotation cell or a high-pressure grinding roll. It was a battered copy of Montgomery’s Introduction to Statistical Quality Control and a stubborn refusal to trust averages.
