May 24, 2016· Electrowinning is a widely used technology in modern metal recovery, mining, refining and waste water treatment applications. Electrowinning is one of the oldest electrolytic processes known and was first introduced in 1807 by English chemist Humphry 66 long years the first commercial refinery Balbach and Sons Refining and Smelting Company adopted the electrowinning .
This process is completed after every strip to remove the gold sludge. for that reason, EC series electrowinning cells have an incorporated anode and cathode slide system that enables the easy cleaning and sludge removal to take place within the cell. This system effectively removes most of the manual labour from the electrowinning process.
Electrowinning is the recovery of metals, such as gold and silver, from solution by passing a current through the solution. Electrons from the current chemically reduce the gold and/or silver ions, to form a solid metal compound on the cathode.

Electrowinning Systems: RotaCat™ 12 Series (5 lbs of copper per day) Electrowinning is very similar to electroplating. Electric current is run through a solution with metal dissolved in it and the metal plates out onto the negative electrode (cathode).
Electrowinning from sulfate solutions is similar to that of electrowinning of nickel, and is discussed in Chapter 26. The major difference between nickel and cobalt electrowinning is that cobalt can be plated from sulfate solutions in cells with or without a separator between anode and cathode compartments.
Some friends are operating a small carbon elution plant. Their gold electrowinning processes 300kg of carbon per month. They have lowpressure boilers and usually leave the carbons in for 48 hours per elute. They test the pH strength every morning and every evening and it usually reads between 12
Electrowinning and smelting are the final stages of gold production. The concentrated gold solutions produced in the elution circuit (pregnant eluate and by the Sunrise Reactor, are passed through the electrowinning cells which converts the gold ions (charged gold particles) in the solution into solid gold.

Electrowinning of gold is regarded as a mature technology; hence, full revision and update of this chapter from the first edition version was not warranted. Some comments on research and operational improvement focus in the past decade are given in the Addendum–Editor''s Note at .
Electrowinning is the electrodeposition of metals from their ores that have been put in solution via a process commonly referred to as leaching. The most common electrowon metals are lead, copper, gold, silver, zinc, aluminium, chromium, cobalt, manganese, and the rareearth and alkali metals.
