Electrowinning is defined as the cathodic deposition of metal, in this example copper, from a copper bearing solution by the passage of an electric current current using an insoluble anode. For copper the electrowinning reaction reaction is: CuSO4 + H2O ⇒ Cu + ½O2 + H2SO4 The overall reaction is the combination of two electrochemical half reactions. The cathodic reaction is: Cu++ + 2e ...
gold recovery, large amounts of activated carbon along with commensurately larger processing plants need are required. 1, 2 Thus final reduction of precious metals from leach solutions leads to one of two processing schemes. The first one shown in Figure 1, or some variant thereof, is usually the one chosen for high gold ores.
PMPC specializes in the gold electrowinning or electrolytic recovery of heavy and precious metals from many different types of solutions with a wide range of pH. For 40 years, we have been developing reclamation and recycling technology offering innovative solutions to electrolytic metal recovery problems including gold, palladium, silver and more.
M. Costello, in Gold Ore Processing (Second Edition), 2016. Automatic CurrentControl Rectifiers. An electrowinning cell is effectively a directcurrent resistance unit. One of the current carriers is the gold–deposition reaction.
The experimental study consisted of designing a cilindrical electrowinning cell and to observe the behavior of different variable on the recovery and selectivity of the electrowinning of gold process.
Gekko''s highvolume electrowinning cell is designed to capture more metal. It achieves highefficiency gold and silver extraction from leach and other pregnant solutions. This highquality device permits greater process uptime, higher mineral yields, less washing and efficient cathode cleaning.
To a great extent, the calculations made to size a standard gold electrowinning cells are based on data and models reported by Roger Paul of Mintek in SA. Extensive plant data collected and interpreted by Mike Costello (Australia) has been used to further enhance the methodology used to size common gold EW cells. Discussion presented is based ...
West Province. The mine produces around 450 kg of gold a month. The ores from the mine are treated in a separate stream at Kopanang Gold Plant. The Kopanang Gold Plant is a modern plant that uses millleachCIP electrowinning processes. The gold from the electrowinning process is smelted centrally in another plant situated 5 km away from Kopanang.
Most process engineering companies readily design and build specification elution and electrowinning facilities for new goldprocessing plants. In gold ore–processing applications, some research focus has been on the influence of impurities such as copper,1., 2., 3. calcium, 4 and anode impurities5., 6. on gold electrowinning efficiency ...
currently operating plant. Process overview and description The CIP process A blockflow diagram of a typical CIP plant for a nonrefractory gold ore is shown in Figure 2. Table I and Table II illustrate the capital and operating cost breakdowns for a typical South African gold plant. These figures are not a standard but reflect the nature of ...
Electrowinning is an electrochemical process used to reduce the metal cations to the cathode surface of an aqueous solution derived from the chemical leaching process. Electrowinning or often referred to as electroextraction is the electrodeposition of metals from ore .

Michael L. Free, Michael Moats, in Treatise on Process Metallurgy: Industrial Processes, 2014. Electrowinning. Electrowinning is the process of "winning" metal from solution using an applied voltage. Gold electrowinning is usually performed in relatively small vessels or cells that are about 1 m long and contain less than 1 m 3 of solution.
The remaining gold in ore is sent to cyanidation followed by carbon in pulp (CIP) gold recovery. After carbon stripping, the gold is processed through electrowinning cells prior to gold pouring. The overall gold recovery is estimated to average between 9192% for the life of the mine.
High quality gold and precious metal electrowinning cells. Manufactured from brushed finish 304 grade stainless steel. Internally rubber lined the cells are equipped with punch plate 316 grade anodes and cathode frames. Cathode frame support either wrapping of mild steel or stainless steel wool for plating and sludging operations respectively, or alternatively accommodate premanufactured ...
Gekko''s electrowinning cell has been specifically designed to handle high silvercontaining solutions and is highly recommended. Gekko also use OEM cells, when appropriate. For lower grade pregnant solutions, a resinbased, carboninsolution or zinc precipitation (Merril Crowe) process, as part of the overall flowsheet design, is suggested.

Process of Electrowinning of Gold. The process of electrowinning of gold has the following five advantages faster electrolysis lower tailings grade safe and reliable operation process high degree of system automation and good economic benefits Therefore it is widely used in gold processing plants
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.
