Magnetic Separation Method - Mineral Processing & Metallurgy

Magnetic Separation Method. Magnetic separation is a process used to separate materials from those that are less or nonmagnetic. All materials have a response when placed in a magnetic field, although with most, the effect is too slight to be detected. The few materials that are strongly affected (magnetised) by magnetic fields are known as ...

Gold parting - Wikipedia

Separation of gold from silver was not practised in antiquity prior to the Lydian Period (12th century BC to 546 BC). 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.
