    en.wikipedia.org/wiki/Cobalt_extraction

    Cobalt extraction refers to the techniques used to extract cobalt from its ores and other compound ores. Several methods exist for the separation of cobalt from copper and nickel . They depend on the concentration of cobalt and the exact composition of the ore used.

  3. Solvent extraction and electrowinning - Wikipedia

    en.wikipedia.org/wiki/Solvent_extraction_and...

    The copper is extracted from the solvent with strong aqueous acid which then deposits pure copper onto cathodes using an electrolytic procedure (electrowinning). SX/EW processing is best known for its use by the copper industry, where it accounts for 20% of worldwide production, but the technology is also successfully applied to a wide range of ...

  4. Copper extraction - Wikipedia

    en.wikipedia.org/wiki/Copper_extraction

    Extraction processes for secondary copper sulfides and low-grade ores includes the process of heap bioleaching. Heap bioleaching presents a cost efficient extraction method that requires a less intensive energy input resulting in a higher profit. [33] This extraction process can be applied to large quantities of low-grade ores, at a lower ...
