We recently had an interview with Chemours (Link to Part 1 here), a leading supplier of sodium cyanide to the mining industry. Our CEO, Benedikt Kirchgaessler, and Jackson Briggs, Marketing Manager for Mining Solutions at Chemours, discussed how novel technologies like CyanoGuard's can radically improve the well-established gold cyanidation process and help gold mines to become more efficient.
Here are our six key takeaways from the interview.
The use of cyanide in gold recovery has been a controversial topic in the face of social and environmental concerns, especially after spillage accidents as seen in Baia Mare in 2000 . This event not only triggered stricter regulations around the use of cyanide in mining, some countries eventually passed federal laws that banned gold cyanidation. Since then, innovations and new technologies have emerged, advocating cleaner and more sustainable means of leaching gold. Although some of these cyanide-free gold leaching innovations have been tested in mine sites, few were able to offer the economics and effectiveness as seen with cyanidation. Below, we explore some questions around cyanide-free gold leaching to get an understanding of this controversy and what it means for mining companies.
