Global Mining Guidelines Group (GMG) has announced the publication of the Introduction to Geometallurgy white paper, a foundational resource designed to, it says, introduce and support the implementation of geometallurgical principles in mining projects.
Geometallurgy is an interdisciplinary practice essential for evaluating and optimising mining operations. It focuses on the spatial characterisation of ore and non-ore types within a deposit, considering their impact on processing, mining performance and environmental sustainability. The white paper is designed to familiarise practitioners with the discipline and consolidate key geometallurgical elements into a single document, providing a roadmap for future GMG guidelines in this area.
“Well-structured geometallurgical programs are essential for optimizing mining processes and ensuring projects meet plan and budget goals, particularly in the face of complex orebodies, cost pressures and ESG priorities,” Keith Merriam, Project Lead and Technical Director, Processing, Teck Resources Limited, says. “By thoroughly characterising orebody variability and integrating best practices, companies can make informed decisions throughout the mine life cycle – from exploration to closure – enhancing operational efficiency and value.”
The white paper provides an overview of critical elements including:
- Common data reporting;
- Representative sampling;
- Geological characterisation;
- Metallurgical and environmental characterisation;
- Data consolidation and quality assurance;
- Model development and evaluation;
- Project optimisation; and
- Reconciliation.
The white paper will also serve as a bridging document for two complementary guidelines:
- Representative Sampling Guideline: This guideline will provide clear, actionable considerations for geometallurgical sampling, encompassing the evaluation of sample representativity, sample selection and sample management. It will include guidance, case studies demonstrating practical applications and examples of templates to streamline processes; and
- Common Data Reporting Guideline: This guideline will aim to establish robust data reporting standards, including user guides for common geometallurgical and mineralogical tests. The guidance will focus on data representation, format, definition, structuring, tagging and reporting for key processes, such as comminution, flotation, leaching, mineralogy and hyperspectral analysis.
Heather Ednie, CEO, GMG, said: “This white paper is a cornerstone resource that not only introduces geometallurgy to those new to the field but will also support the development of best practices through the complementary guidelines under the geometallurgy umbrella. Together, these resources will empower the mining industry to harness the full potential of geometallurgy.”
The white paper and the forthcoming guidelines reflect GMG’s commitment to fostering interdisciplinary collaboration and innovation in mining, GMG says. By uniting key concepts and providing actionable guidance, these resources aim to enhance operational efficiency, sustainability and data-driven decision making.
