Silver Recovery Through Molten Salt Destruction of Sludges and other Solids

Abstract

Secondary recovery of precious metals from sludges is applied to minimize the wastes, reduce the waste classifications, and recover the metals. Molten salts, operating at moderate eutectic temperatures, are used to solubilize the sludges, whereupon the precious metals are reduced and gravity separated from the flux. Additional decomposition reactions occur that degrade the remaining flux contaminants. Applications are discussed for various silver bearing solids.
