The Cyanide Diagnostic: Chemistry, Compliance, and Gold Recovery
Loading player...
Guest: Wiehan, Metallurgist & Mineral Processing Specialist (Maelgwyn Mineral Services)
Cyanide is the undeniable backbone of global gold extraction, yet its reputation often sparks intense debate and misunderstanding.
In this episode of The Mining Pulse, we strip away the fear and look strictly at the data, running a full operational diagnostic on how this powerful chemical is managed safely and efficiently on site.
We are joined by Wiehan from Maelgwyn Mineral Services to explore the delicate chemistry of gold leaching, the stringent frameworks of the International Cyanide Management Code, and the diagnostic test work required to optimize a leach circuit without destroying a project's economics.
In this episode, we diagnose:
•The Reputation vs. Reality: Why cyanide remains the most efficient method for extracting gold worldwide despite its complex public profile.
•The Chemistry of the Circuit: Understanding free cyanide, weak acid dissociable (WAD) cyanide, and the critical role pH plays in keeping the chemical stable and preventing toxic gas releases.
•The Cyanide Code: How the International Cyanide Management Code acts as the ultimate site safety metric, managing risks from production and transport through to destruction and tailings deposition.
•Destruction & Detoxification: Unpacking the methods used to neutralize cyanide—like the SO2/Air process and Caro's Acid—before waste ever hits the tailings dam.
•Circuit Troubleshooting: Why diagnostic test work and laboratory troubleshooting are the essential first stops for any mine facing poor gold recoveries or soaring reagent bills.
