While theoretical knowledge is vital, it is applied through powerful software tools. For the modern mineral engineer, proficiency in these platforms is essential:
1. Data Characterization and Exploratory Data Analysis (EDA) Statistical Methods For Mineral Engineers
The field is increasingly adopting sophisticated statistical frameworks:
“Rubbish in, rubbish out” is a maxim that holds particularly true in mineral engineering. Statistical methods for mineral engineers begin not with advanced modelling but with rigorous data quality assurance (QA/QC). This public link is valid for 7 days
When optimizing a metallurgical process—such as determining the ideal flotation reagent regime or leaching temperature—changing one factor at a time (OFAT) is inefficient and misses critical interactions between variables. Design of Experiments (DoE) solves this problem. Factorial Designs Evaluates
Accurate statistical analysis is impossible without representative sampling. Pierre Gy’s Sampling Theory serves as the gold standard for mineral engineers to minimize error when diverting a small stream portion for laboratory analysis. Components of Sampling Error Can’t copy the link right now
Unlike pure statistics texts, this book focuses on regression for the purpose of prediction and control.
Accurate data collection is the foundation of any statistical analysis. In mineral processing, Pierre Gy’s Sampling Theory serves as the gold standard for understanding and minimizing sampling errors. The Total Sampling Error (TSE)
PLS is ideal when you have many collinear predictors (e.g., XRF elemental intensities) and want to predict an assayed grade. PLS finds latent variables that maximize covariance between predictors and responses.
