Statistical Methods for Mineral Engineers In modern mineral processing and extractive metallurgy, operations face declining ore grades, complex mineralogy, and strict environmental regulations. To maintain profitability and efficiency, facilities must move away from trial-and-error methodologies. Statistical methods provide mineral engineers with the mathematical framework needed to optimize throughput, maximize recovery, and minimize processing costs. This article explores the core statistical tools utilized in mineral engineering, from fundamental sampling theory to advanced multivariate process control. 1.
