gold cyanide processing - castersmilieu

The gold cyanidation process is a primary method of gold beneficiation. Activated carbon is a critical component in the beneficiation of gold ore, allowing this widespread process to occur because of its ability to recover gold from the gold-cyanide complex. Depending on the deposit, some silver ores may also be processed via cyanidation. Read More
