chemical processes
The relevant chemical processes used in manufacture, such as purification, seperation, emulgation and dispergation processing.
Assayers test and analyse precious metals such as silver and gold to determine the value and properties of components using chemical and physical techniques. They also seperate precious metals or other components from other materials.
