• metallurgy Separation of the Metal Infoplease

  Another method for the separation of gold and silver is the so-called cyanide process . The Parkes process which is based on silver being soluble in molten zinc while lead is not is used to free silver from lead ores. Since almost all the metals are found combined with other elements in nature chemical reactions are required to set them free.

  Separation of Mixtures. Since they are formed by physically combining substances mixtures can be physically separated. For example if a copper sulfate solution is boiled the water evaporates away and the copper sulfate powder remains. The formation of a mixture is a physically reversible process.

• Methods for Separating Mixtures Chemistry for Non-Majors

  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.
