What is metal and nonmetal extraction?

Answer 1

A method for separation and recovery of metals and metal oxides from industrial minerals and waste materials

Extraction from the metal ore involves reduction of the metal,

and electrons can reduce any metal ion.

metal ions + electrons metal atoms (reduction).

non-metal ions - electrons non-metal atoms (oxidation).

The electrodes are often made from graphite.

The liquid which conducts electricity is called the electrolyte.

The amount of electricity needed to produce a particular mass

of metal (or non-metal) can be calculated.

The negative electrode, called the cathode,

will attract positively charged metal ions.

The metal ions collect electrons from the cathode

and are discharged as metal atoms.

The positive electrode, called the anode,

will attract negatively charged non-metal ions.

The non-metal ions lose electrons to the anode

and are discharged as non-metal atoms.
