Filtration is a good method for this (you can decant also, but this is crude)
The meaning of undissolved is not disintegrated, not dispersed in the liquid.
Decantation is commonly used to separate a mixture of a liquid and a solid component, where the solid settles at the bottom. Examples include separating sand from water, separating tea leaves from brewed tea, or separating settling chalk from water.
a suspension
This technique is called filtration or decanting, depending on how you do it.
Evaporation is used to heat the liquid mixture to a temperature where one liquid evaporates but the other remains a liquid. The evaporated liquid is then condensed back into liquid form by cooling it. This process separates the two liquids based on their different boiling points.
it is called evapourating
The act or process of filtering; the mechanical separation of a liquid from the undissolved particles floating in it.
a liquid mixture in which the minor component (the solute) is uniformly distributed within the major component (the solvent) or the action of separating or breaking down; dissolution
Desalination
The meaning of undissolved is not disintegrated, not dispersed in the liquid.
Each solute has a limit of solubility in a liquid, at a given temperature and pressure. The undissolved solute is a solid residue.
settling
Decantation is commonly used to separate a mixture of a liquid and a solid component, where the solid settles at the bottom. Examples include separating sand from water, separating tea leaves from brewed tea, or separating settling chalk from water.
a suspension
If the matter is undissolved then it will form a precipitate or suspension. To remove the undissolved matter you would filter it through filter paper or similar.You could centrifuge it first if you had the equipment. Centrifuging makes the particles settle to the bottom and then you can decant (pour off) the liquid from the top.
