GC 6×12-GM

Granular Activated Carbon For Gold Mining

GC 6×12-GM is a virgin granular activated carbon. Derived from the finest grades of coconut shell, its high activity and hardness as well as its low platelets content make it ideal for many vapor phase applications including the extraction of gold in mining.

Wet activated carbon removes oxygen from air causing a severe hazard to workers inside carbon vessels. Confined space/low oxygen procedures should be put in place before any entry is made. Such procedures should comply with all applicable Local, State and Federal guidelines.
