ELECTROWINNING. Electrowinning of gold from the pregnant solution is done on a batch basis. The solution pH is increased to 12 by the addition of sodium hydroxide and electrowinning is started. Solution is circulated through electrowinning and back to the pregnant solution tank until acceptable barren levels are achieved. The solution is then discarded.
