Why does gold react with cyanide and sodium hydroxide and what is the chemical reaction''s impact on gold''s atomic structure and bonding? What I think is since in the ''flotation'' process, when the water, chemicals and other substances are added, gold isn''t affected and neither is the pyrite, but when the cyanide and caustic acid is mixed with the slurry, it separated both substances, then the
