From Geology to Closure: How Clays Influence Mining

November 23, 2022


Join us for a one-day, hybrid course that offers participants a comprehensive understanding of how clays influence mining, from the geology of a new development to closure. The course is developed in collaboration by Dr. Heather Kaminsky from NAIT’s Technology Access Centre for Oil Sands Sustainability, Andrew Vietti from Vietti Slurrytec and Lois Boxill, an independent mine closure specialist.

Clays and clay minerals are present in most mine sites across the globe, but do you understand how they impact the mining process from geological exploration, through the mining and processing stages, and finally towards reclamation? These unique materials can challenge your extraction and thickening processes, as well as your tailings storage facility. In this course, you will learn:

The properties of clays and clay minerals, including nomenclature, surface area, surface chemistry and plasticity.
Why it is important to measure clays, which methods are available, when to use multiple methods, and how to interpret results.
The implications of clay properties on extraction and tailings management, including a review of clay-water interactions and DLVO theory.
The implications of clay properties on deposits, geotechnical performance and closure.
