  2. Electrowinning - Wikipedia

    en.wikipedia.org/wiki/Electrowinning

    Electrowinning, also called electroextraction, is the electrodeposition of metals from their ores that have been put in solution via a process commonly referred to as leaching. Electrorefining uses a similar process to remove impurities from a metal.

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

    Solvent extraction and electrowinning (SX/EW) is a two-stage hydrometallurgical process that first extracts and upgrades copper ions from low-grade leach solutions into a solvent containing a chemical that selectively reacts with and binds the copper in the solvent.

    In electrorefining, decarburization process happened in electrochemical cell that composed of inert electrode, slag and steel. During the process, current passing through the cell and made slag and steel melted. Oxygen ion from slag decompose and oxidize carbon on steel and to form CO. That decarburizing reaction is occurred in three steps as ...

    A modern copper refinery tankhouse using IsaKidd technology. The IsaKidd Technology is a copper electrorefining and electrowinning technology that was developed independently by Copper Refineries Proprietary Limited (“CRL”), a Townsville, Queensland, subsidiary of MIM Holdings Limited (which is now part of the Glencore group of companies), and at the Falconbridge Limited (“Falconbridge ...

    The metal will be exchanged from the organic to the electrolyte. The resulting streams will be a stripped organic and a rich electrolyte. The organic stream is recycled through the solvent extraction process while the aqueous streams cycle through leaching and electrowinning [clarification needed] processes respectively. [citation needed]

    Electrowinning is generally recovery from a leach solution with an inert anode. Electrorefining involves dissolving the anode, dropping out the impurities to solution or sludge, and re-plating the metal being refined on the cathode (nominally free of impurities).

  9. Electrolysis - Wikipedia

    en.wikipedia.org/wiki/Electrolysis

    The terms for this are electroplating, electrowinning, and electrorefining. When an ion gains or loses electrons without becoming neutral, its electronic charge is altered in the process. For example, the electrolysis of brine produces hydrogen and chlorine gases which bubble from the electrolyte and are collected.
