In a non-precious metal (especially zinc) dissolution apparatus, the metal is brought into electrically conductive contact with one or more materials selected from Co, Ni, their alloys and compounds (preferably oxides and/or mixed oxides), preferably by loading the metal into a basket made of or coated with the material. Preferably, the basket is a nickel-coated steel basket and the non-precious metal is zinc. Also claimed is a non-precious metal (especially zinc) dissolution process using the above apparatus.
