Introducing Project Proposals Around Geometallurgy

The industry’s need for a comprehensive, common guideline for geometallurgical sampling has become a more critical challenge because of the lack of information publicly available. With common guidance available, it can bridge the gap of limited accessible information, ensure representativity and confidence, enhance transparency in geometallurgy models, and foster stakeholder trust in sampling methodologies and outcomes.

The Sample Representativity in Geometallurgy project aims to develop a guideline that provides clear, actionable considerations on geometallurgical sampling, encompassing representativity, sample selection and management. Deliverables may include a comprehensive guideline, case studies demonstrating the application of these principles, and tools and templates when implementing concepts from the guideline.

A fundamental principle of geometallurgy is to test a large number (high volume) of samples and to relate metallurgical response to ore properties. The large number of samples and tests typically results in large datasets that contain valuable data. There are no commercial applications specifically tailored to managing geometallurgical and mineralogical data. One reason for this is the lack of standardization in the reporting of geometallurgical and mineralogical test results which can create a barrier to the development and commercialization of data management applications.

The Guideline for Common Data Reporting in Geometallurgy project aims to develop data reporting guidelines including templates and user guides for common geometallurgical and mineralogical tests, as a key enabler for efficient consumption of data. The guidelines are intended to include representation, format, definition, structuring, and tagging. The expectation is to develop reporting guidelines to cover the most comminution, flotation, leaching, mineralogy (x-ray diffraction, automated minerology), and hyperspectral analysis.

These topics were selected as the first phase of work by the Geometallurgy sub-committee, which includes 11 mining companies along with OTMs, consultants and academics who are building a collaboration roadmap. Project proposals will be submitted to the Mineral Processing steering committee for official project launch in Q2.
