Gold Mining and Processing: Everything you Need to Know
A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver. This process removes 93% of the gold and 70% of the silver.

Should cyanide still be used in modern-day mining?
The toxic chemical is still widely used for the processing of certain ores, most notably gold, but should cyanide be phased out of mining, and what are the alternatives? Share Article Toxic sodium cyanide has been used in gold mining since 1887, and it remains the primary reagent in use for gold processing today because it allows for efficient extraction of gold from low-grade ore.
