  • Silver processing Britannica

    A process routinely employed in the fire assaying of gold ores is the addition of silver prior to fusion of the ore in order to ensure that the silver content of the final bead is high enough to dissolve. This is called inquartation and the separating of silver and gold by leaching with nitric acid is referred to as parting.
