Chemical Reactions with Gold by Andy Bui on Prezi

Transcript of Chemical Reactions with Gold 3 Chemical Reactions With The Extraction of Gold By: Sagar Kaushal and Andy Bui

Aug 25, Can anyone provide me with the chemical processes involved in Gold extraction, more specifically i need the anode/cathode reactions? Also why is CN exactly used, and env problems associated with this process? Please do not provide me with a wikipedia link, ive already checked it out and it doesnt have the exact anode/cathode reactions.
