Decantation Definition. Decantation is the process of separation of liquid from solid and other immiscible (non-mixing) liquids, by removing the liquid layer at the top from the layer of solid or liquid below. The process can be carried out by tilting the mixture after pouring out the top layer. This process can also be used to separate two ...

magnetic separation, there are also practical aspects that must be taken into account as well, in order to achieve the separation desired. These are the size and specific gravity of the particles, which will necessitate a relatively stronger magnetic field to remove a large, heavy particle than would be required for a small, light particle.

SEPARATION TECHNIQUES. If a substance does not dissolve in a solvent, we say that it is insoluble. For example, sand does not dissolve in water – it is insoluble. Filtration is a method for separating an insoluble solid from a liquid. When a mixture of sand and water is filtered: the sand stays behind in the filter paper (it becomes the residue)
