Activated carbon plays a vital role in modern gold extraction and recovery systems and is widely known as the “efficient catcher” for dissolved gold. In cyanide-based gold processing, activated carbon—particularly high-quality coconut shell charcoal—serves as the primary medium for capturing gold cyanide complexes from leaching solutions. 

Sodium cyanide plays a central role in modern gold metallurgy and is widely recognized as the “chemical key” for gold dissolution. For more than a century, cyanide-based leaching has remained the dominant technology for extracting gold from ores, accounting for the majority of global gold production.
