اقرأ أكثرThe large volumes of material are dumped onto a lined leach pad, and cyanide solution is sprayed over it. The cyanide binds with the gold and causes a solution enriched with gold to settle at the bottom. The gold can then be extracted from that solution. Environmental risks of large-scale open pit mining are complex and uncertain.
