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.
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.
settling
When separating a liquid from undissolved solids, techniques such as filtration or decantation can be employed. Filtration involves passing the mixture through a filter paper or membrane that retains the solid particles while allowing the liquid to pass through. Decantation, on the other hand, is a method where the liquid is gently poured off from the solid sediment, taking advantage of differences in density. Both methods effectively separate the components based on their physical properties.
To separate mixtures by boiling, you can use the process of distillation, which relies on differences in boiling points of the components. When the mixture is heated, the component with the lower boiling point vaporizes first. This vapor is then collected and condensed back into a liquid form, effectively separating it from the other components that remain in the original mixture. This method is commonly used for separating liquids or liquid-solid mixtures.
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.
