DEF

The extraction of gold and silver from their ores. The process is only applicable to these metals. The solvent is a weak solution of sodium or calcium cyanide which, when aerated, easily dissolves the precious metals. They are then recovered by agitating the "pregnant" solution with aluminium or zinc in the form of dust or shavings and filtering out the precipitate which is then melted and cast into bars (bullion).
