A new way of extracting copper
The closest industrial process to the electrolytic copper extraction they hope to see is aluminum production by an electrolytic process known as Hall-Héroult process, which produces a pool of molten aluminum metal that can be continuously tapped. "The ideal is to run a continuous process," Chmielowiec says.
