The general classes of colloids are sols (solid particles dispersed in a liquid), gels (cross-linked networks of solid particles dispersed in a liquid), and emulsions (liquid droplets dispersed in another liquid).
Decantation is suitable for separating heterogeneous mixtures of a solid and a liquid, where the solid settles at the bottom of the container. Examples include separating sand from water, or sediment from a suspension of particles in a liquid.

A gas is not a liquid or a solid.
Whether the solid will float or sink in a solid-liquid mixture depends on the relative densities of the solid and the liquid. If the density of the solid is greater than that of the liquid, then the solid will sink. If the density of the solid is less than that of the liquid, then the solid will float.
