To recover <60μ gold, conventional wisdom invokes either extreme gravitational devices such as advanced centrifuges or chemical leaching methods such as cyanide. So complete is the dominance of advanced centrifuges and cyanide leaching that other methods have become neglected and overlooked.

Ion Exchange Ion exchange (IX) has been used most often with pre- cious metal plating (silver and gold) and requires a special configuration to recover the strongly complexed metal cya- nides. IX is commonly used in surface finishing to recover metal and recycle rinsewater and is typically used in a cation-anion configuration.
