40’Electro Winning/Electro Deposition: continued 4
• -->>cont: Part of H3(less wasted ion deposition, Metal recovery from wastewater):
♛ElectroWinning(EW)/ElectroExtraction/Electrolytic Refining:
• Market focus in Russia is often more on wastewater treatment than metal process(НПП
«Медиана-Эко», "ГидроСтройПроект" gsp-bmt, Компания «ЛВ-Инжиниринг»+),
• ii-CIRCULATING FLOW: Generally significantly more effective than conventional flat plates
●Vortex Water Flow around Cylinder Electrode: for high efficiency performance(prevent
target metal ion depletion zone formed around electrode) down to
10ppm(emewCorporation +),
• ●Cyclic Electrowinning/Precipitation CEP: super efficient ability to selectively remove copper,
iron, zinc, lead etc & potentially still profitable process as low as 5ppm by effective Spouted
Electrode, Hydrogen overvoltage control, pH etc handling(Eltron Water ElectroWinner),
Nickel & Cobalt wastewater strength - likely pioneer of swirling tech(De Nora+),
China is generally advanced along with other water tech by taking on rotating water tech
(陝⻄西Elade 新材料料技術有限公司, 浙江科菲科技股份有限公司 Ke-Fei+),
• **Electro Winning itself is cleantech, but depends on how to regard entire mining process
that includes grounding ores, leaching(dissolving minerals, cyanide[a Carbon-Nitrogen
compound by triple bond] is used particularly for gold and silver) and Electro Extraction, it
might not fit to clean technology category.
