♛ElectroWinning(EW)/ElectroExtraction/Electrolytic Refining/Electrolytic Metal
Recovery(EMR): also categorized as part of HydroMetallurgy. Chemically reduce
metal ions to form solid metal on cathode. Although one of oldest mainstream
electrolytic process & usually the most core part of metal smelting/concentration/
production step to recover/adsorb/concentrate many metals from pregnant
aqueous solutions-electrolyte(Gold/Silver/Copper are easier with positive
electropotential while Zinc/Cobalt/Lead etc are harder with negative
electropotential[Aluminum process uses no water]), it is underused at mining, PCB
recycling, or electroplating wastewater stage effluent cleaning + metal recovery
purpose combined partially due to conventional EW's ineffectiveness at low ore
concentration. And at the Western Mainstream media level this is still often treated
as "revolutionary new technology".
• i-FLATPLATE TYPES: Combine Ion-Exchange resins and stripping them with EW
hence no resin regeneration(i.e. cleaning, often uses chemical itself to do so) is
needed(Gekko Systems+), copper focus: after Solvent extraction and
ElectroWinning(SX/EW) process wastewater(Fluor+), PCB recovery, Jewellery etc
sector focus(Precious Metals Processing Consultants+), -->>cont:
