A new way of extracting copper MIT News
2017-6-28 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.

2019-9-26 The remaining mixture is a molten copper sulfide referred to as matte. The next step in the refining process is to oxidize liquid matte in order to remove iron to burn off sulfide content as sulfur dioxide. The result is 97-99%, blister copper. The term blister copper comes from the bubbles produced by sulfur dioxide on the surface of the copper.

Phytoextraction and bioleaching (bacterial) are two relatively new methods of extracting metals that rely on biological phenomenon. Both of these methods avoid the significant environmental damage caused by the more traditional methods. They are however very slow and also do require either displacement or electrolysis to make the final product.
