Lead and leadalloy anodes for electrowinning metals such as zinc, copper, lead, tin, nickel and manganese from sulfuric acid solutions, whereby the electrodes are processed by a repetitive sequence of cold deformation and recrystallization heat treatment, within specified limits of deformation, temperature and annealing time, to achieve an improved microstructure consisting of a high frequency .
Optimization of Industrial Copper Electrowinning Solutions. Laboratory testing using an industrial electrowinning solution was performed to determine the best cell efficiency. The variables tested were solution flow rate, recycle ratio, reagent addition, combinations of guar and thiourea, and amounts of acid mist suppressant.
May 18, 2016· The Electrowinning Process: Part One Posted on May 18, 2016 by Total Materia The electrowinning process is a relatively traditional method to recover waste metals through the rinse system and at the same time reduce waste water generation and chemical discharge.

Copper Electrowinning. Typical of electrowinning from aqueous solutions is copper electrowinning. The electrolyte entering the cells contains 25–60 g l1 of copper, 50–180 g l1 of sulfuric acid, and 5–10 g l1 of iron salts (Habashi, 1998). It is produced by leaching of copper ores, with solution purification by solvent extraction.
