Polypseudohalogen-based ionic liquid offers innovative way to recycle electronics

Two new polypseudohalogen compounds derived from cyanogen bromide have the unusual property that they can dissolve gold at room temperature. The discovery could lead to safer chemicals for leaching gold and other noble metals from ore, as well as offer a new way to recover and recycle metal from electronics waste.
