    Chemistry: Separating Mixtures

    One of the simplest methods used to separate mixtures is filtration. If one of the components is a liquid and the other is a solid, filtration is as easy as pouring the whole mixture through filter paper. An everyday example of filtration can be seen in a coffee maker, where the coffee passes through a paper filter but the grounds do not.

    How to Separate Silver & Gold by Cementation

    Older processes explaining how to go about separating silver from gold by cementation were carried on practically in two ways, the first by heating gold for a long time with a mixture which evolved nitric acid on heating, and an absorbent into which any fusible salts ran; the mixture in the second method contained common salt as an essential ingredient, and some material which would assist in ...

    Separation of the Components of a Mixture

    A third method of separation is called filtration. This is the process of separating a solid from a liquid by means of a porous filter which allows the liquid to pass through but not the solid. This has nothing to do with solubility or ability to sublime, but rather simply the physical phase of the substances and the permeability of the filter.

    A mixture can contain solids, liquids and/or gases. The components in a mixture are not chemically joined; they are just mixed. That means we do not need to use chemical reactions to separate them. Mixtures can be separated using physical methods alone and that is what this chapter is all about: how to separate mixtures.

    Extracting Gold | HowStuffWorks

    When workers add a chemical mixture known as flux to the molten material, the gold separates from the metal used to make the terminals. Workers pour off the flux and then the gold. Molds are used to transform the liquid gold into solid bars called doré bars. These low-purity bars are then sent to refineries all over the world for further ...

    Gold parting - Wikipedia

    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 ...
