Cornstarch Replaces Cyanide In Clean New Gold Extraction Method. Scientists accidentally discover a new way to isolate gold that is much safer than existing processeswhich use toxic cyanide.
The gold cyanidation process is a primary method of gold beneficiation. Activated carbon is a critical component in the beneficiation of gold oreallowing this widespread process to occur because of its ability to recover gold from the gold-cyanide complex. Depending on the depositsome silver ores may also be processed via cyanidation.
