US Patent for Method for precipitating copper metal from …

To recover metallic copper from the dilute copper sulfate solution, it is also a conventional practice to precipitate the copper metal out from the solution using scrap iron for the precipitant. The process of precipitating copper metal from copper bearing solutions using scrap iron is generally called "cementation" and the precipitate is called "cement copper".

The precipitated copper is termed "cement copper". The iron ordinarily is added to such solution in the form of sheet-iron scrap, cast iron bars, or iron sponge. In achieving precipitation, it is important that the surface of the iron be constantly kept clean; that is, the precipitated copper should be constantly separated from the iron, so that further copper may precipitate thereon.
