When workers add a chemical mixture known as flux to the molten material, the gold separates from the metal used to make the terminals. Workers,

Separating Mixtures | Physical Separation Techniques,

Separation Techniques. Physical separation techniques are based on the physical properties of the substance. These physical properties can be physical state, magnetic and electrical properties, specific gravity, density, melting point, boiling point and solubility.
