Copper and gold recovery from CPU sockets by onestep

Mar 10, 2019 Gold mainly exits in the electrolyte, and little gold can be electrodeposited. Besides, the results of XRD and SEM show that the obtained metal powder is mainly copper and copper powder particles are mainly dendritic. On the basis of these results, slurry electrolysis could be applied to the recovery of copper and gold from electronic component.

Gold Refining From Gold Ore to Dor World Gold Council

The Miller process uses gaseous chlorine to extract impurities when gold is at melting point impurities separate into a layer on the surface of the molten purified gold. The Miller process is rapid and simple, but it produces gold of only about 99.5 percent purity. The Wohlwill process increases purity to about 99.99 percent by electrolysis.
