Filtration. Filtration is a separation method used to separate out pure substances in mixtures comprised of particles some of which are large enough in size to be captured with a porous material.Particle size can vary considerably, given the type of mixture. For instance, stream water is a mixture that contains naturally occurring biological organisms like bacteria, viruses, and protozoans.

How to Separate Salt and Sand — 3 Methods

25-1-2020· Three methods used to separate salt and sand are physical separation (picking out pieces or using density to shake sand to the top), dissolving the salt in water, or melting the salt. Probably the easiest method to separate the two substances is to dissolve salt in water, pour the liquid away from the sand, and then evaporate the water to recover the salt.

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.
