摘要
An improvement in the process of producing substantially oxide free copper from copper salts by reacting an acidic aqueous solution which contains the copper salts with a reducing gas at elevated temperature and pressure to precipitate metallic copper. The improvement for producing copper in free-flowing powder form comprises providing in the aqueous solution a finite amount of an addition agent selected from the group consisting of polymeric polyamine compounds having amino groups linked by alkyl groups having 2 to 4 carbon atoms.
