Abstract

Improved method adapted for the continuous precipitation of metal cement (especially copper cement) from an aqueous solution of a first metal (such as copper) mixed with pieces of second metal (such as iron) which is less noble than such first metal. The first metal cement depositing on the second metal pieces is loosened therefrom by means of constant but regulated movement of such pieces, and is separated and collected from the mixture.
