NickelCobalt Electrowinning

Experimental Equipment and ProcedureExperimental Results and DiscussionsElectrowinning from Laterite ProcessingExperimental Cobalt ElectrowinningConclusionMost of the electrowinning tests were conducted in a 4.5-liter acrylic cell, 15 x 20 x 16.5 cm, with a single cathode, 15 x 16 cm, of either titanium or stainless steel and two anodes of lead containing 0.05 pct Ca. The electrode spacing was 5 cm. Electrolyte was pumped to and from the cell by a chemical metering pump, while a small fraction of the metal ion content was deposited. The pregnant feed was stored in a 28-liter tank and was preheated to 50° to 85° C. Electrolyte was circulated wit...

Electrowinning Wikipedia

Electrowinning is the oldest industrial electrolytic process. The English chemist Humphry Davy obtained sodium metal in elemental form for the first time in 1807 by the electrolysis of molten sodium hydroxide.. Electrorefining of copper was first demonstrated experimentally by Maximilian, Duke of Leuchtenberg in
