2. Gold Extraction Process
Cyanide Process
• Cyanide extraction of gold may be used in areas where fine-
gold bearing rocks are found.
• Sodium cyanide solution is mixed with finely-ground rock
that is proven to contain gold and/or silver, and is then
separated from the ground rock as gold cyanide and/or
silver cyanide solution.
• Zinc is added to the solution, precipitating out residual zinc,
as well as the desirable silver and gold metals.
• The zinc is removed with sulfuric acid, leaving a silver
and/or gold sludge that is generally smelted into an ingot
then shipped to a metals refinery for final processing into
99.9999% pure metals

3. Adverse Effect
• Cyanide dumped into rivers as a result of gold
mining can have adverse effects on a river's
ecosystem.
• Lead as a byproduct can have adverse effects on
human health, as illustrated by the case of
northern Nigeria, where 163 people were killed
by lead poisoning in early 2010 as a result of
illegal gold mining.
• The Sulpride Acid Used Can cause bad effects.
