The Tailings Diagnostic: From Mine Waste to Circular Resource
Loading player...
Guests: Dr. Nicolene Roux (Project Engineer) & Fuldre (GM: Projects & Business Development) at Fraser Alexander
Globally, roughly 13 billion tons of tailings are added to surface storage facilities every single year. Traditional reprocessing models focus almost exclusively on extracting hidden grams-per-ton of residual primary minerals, meaning that 99% of that total waste volume goes right back onto the surface. In this episode of The Mining Pulse, we run a comprehensive operational diagnostic on true tailings repurposing with the NextGen team from Fraser Alexander.
Dr. Nicolene Roux and Fuldre join hosts James and Graeme to unpack the "Mine Waste Hierarchy," explore the complex technical and regulatory barriers to commercialization, and outline how forward-thinking operators are leveraging modern digital tools to achieve a "zero waste" industrial future.
In this episode, we diagnose:
•The Mine Waste Hierarchy: Breaking down the inverse pyramid framework from total elimination and reduction to repurposing, recovery, and remediation.
•Repurposing vs. Recovery: Why pulling out residual gold or PGMs doesn't solve the volume problem, and how transforming bulk waste into aggregate or building materials changes the game.
•The Legacy Data Barrier: Navigating the physical heterogeneity and historical record gaps of old waste deposits that block commercial scale.
•Global Success Stories: Examining how international majors like Vale and Rio Tinto successfully qualified and launched sustainable sand and synthetic aggregates.
•The Digital Horizon: Utilizing satellite imagery, old production profiles, and data systems to map, rank, and de-risk legacy tailings facilities.
•Equitable Community SPVs: Moving past simple job creation to structure Special Purpose Vehicles and trusts that give local communities an active equity stake in the logistics value chain.
Stay sharp.
Stay informed.
Stay on the pulse.
