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.

Gold parting is the separating of gold from silver.Gold and silver are often extracted from the same ores and are chemically similar and therefore hard to separate. Over the centuries special means of separation have been invented. The very earliest precious metals had mixes of gold and silver; gold and silver alloy is called electrum.With the advent of coinage, methods had to be invented to ...

The high abundance of iron in iron ore samples causes serious interference in gold determination, whatever the used analytical method is; so gold separation prior to determination is a necessary step. The aim of this work is to separate gold from iron rich samples for spectrophotometric determination.
