Gold parting - Wikipedia

Separation of gold from silver was not practised in antiquity prior to the Lydian Period (12th century BC to 546BC). Material from Sardis (in modern Turkey) is evidence of the earliest use of gold and silver parting in the 6th century. Literary sources and the lack of physical evidence suggest that gold-silver parting was not practised before the mid first millennium BC.

chromatography is a process for separating different components from a MIXTURE. This is achieved by passing a sample mixture (the "analyte") in a stream of solvent (the "mobile phase") through some form of material (the "stationary phase") that will provide resistance by virtue of chemical interactions (not reactions) between the components of the sample and the material.
