Refining of Metals: Distillation, Zone Refining

When we say that gold is 24 carats, what does it mean? It means that the gold is completely absent from impurities, it is entirely pure. Now, this does not happen naturally. Metals extracted or mined always have some impurities in them. The process of removing such impurities is known as refining. Let us learn more.

Thickeners - Solid Liquid Separation

Thickeners. The separation of solids from a liquid by gravity sedimentation has traces to the early days of civilization. The normal practice at those times was to use jars or pits mainly for the clarification of extracted liquids such as wine or olive oil from contaminating insoluble matter. These batch processes required four separate steps:

What type of mixtures can be separated by-

 · You can use filtration to separate a mixture of a solid in a liquid or a solid in a gas. Filtration is a separation process in which a mixture is passed through a filter that allows one component to pass through uninhibited but blocks another component from passing through. In general this method sorts by size, with the filter acting as a barrier that allows smaller particles
