Gold Recovery: In gold mining, activated carbon is used to extract and recover gold from cyanide leach solutions, making it an essential component of the gold recovery process. Energy Storage: Activated carbon-based supercapacitors are emerging as a promising energy storage technology due to their high surface area, electrical conductivity, and ability to store a large amount of charge. Nuclear Power Plants: Activated carbon is used in some nuclear power plants for removing radioactive gases from the air in case of a nuclear accident or leak.
