Separation and Recovery of Components in a Ternary

2014-11-3  In a solution one component is dissolved in another, and they cannot be separated by the physical methods discussed previously. Another physical method, such as heating, can be used. The liquid component is removed by evaporation and the solid component will remain in the container. If we have a mixture of two solids they can be separated by extraction by adding a solvent in which only

2019-5-1  Another 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.
