What is the Difference Between Electrowinning and Electrorefining

The key difference between electrowinning and electrorefining is that in the electrowinning process, the impure metal is in the leach solution, whereas in the electrorefining process, the impure metal is the anode.. Electrowinning is the electrodeposition of metals from the ores that have been put in a solution via leaching. Electrorefining is the electrodeposition …
