Question

What is the difference between electrowinning and electrorefining?

Answer 1

Electrowinning	Electrorefining
The process includes the electrodeposition of metals from its ores through leaching	The process includes the electrodeposition of metals from its ores, by putting them into the solution to remove impurities.
The anodes is inert anode.	The anode is made up of impure metal.
When electric current is pass through the solution from anode to cathode the pure metal is deposited on cathode	The impure metals get oxidized into the solution by the movement of ions, and thus pure metal is deposited on the cathode.
Heavy metals can not be extracted easily through this process.	Heavy metals can be separated from the bulk of Uranium such as Cesium, Plutonium, Strontium
