Tin and silver recovery from wave soldering dross

This process recovered 92% of the silver in the wave soldering dross ingot at a purity of >99.6%. Some 99% of the copper entering the leachate from the copper rod during cementation was recovered by liquid-liquid extraction with 40% LIX84 (dissolved in EXXOL D100). This method could provide a rapid, inexpensive means of recovering pure tin and ...
