Electrolysis can be used to separate ionic substances.

Ionic substances contain positive metal ions and negative non-metal ions .

What is Electrolysis?

TASK:TASK:Draw the diagram

Metals above carbon must be extracted using electrolysis.

Metals below carbon can be extracted from the ore by reduction using carbon, coke, or charcoal.

Gold and silver often do not need to be extracted. They occur native.

The reactivity of a metal determines the method of extraction.
