  Catalysing electrowinning of copper from E-waste: A critical …

  202271 · Multiple elements can be recovered from e-waste, including base metals such as copper (Cu), precious metals such as gold and silver, and critical metals such as palladium and other REEs (Balde et al., 2017). Among them, Cu has accounted for 10–25% of the metal contents in e-waste, which was higher than the Cu content found in raw and …

  A new way of extracting copper - MIT News

  Copper is much rarer, but fortunately can be found in high-grade ores (ones containing a high percentage of copper) in particular places. Because copper is a valuable metal, it is also worth extracting it from low-grade ores as well. Ores are commonly oxides, for example: bauxite (Al 2 O 3) haematite (Fe 2 O 3) rutile (TiO 2). . . or sulfides ...
