1. Filtration: This method uses a filter to separate solid particles from a liquid or gas. The mixture is poured through a filter paper, mesh, or sieve, and the solid particles are trapped while the liquid or gas passes through.

2. Distillation: Distillation is a method used to separate a mixture of liquids by heating them to their boiling points and collecting the vapor that is produced. The vapor is then cooled and condensed back into a liquid, resulting in the separation of the different components based on their boiling points.

3. Evaporation: Evaporation is the process of separating a liquid from a solid by heating the mixture. The liquid evaporates, leaving behind the solid. This method is commonly used to separate salt from saltwater.

4. Decantation: Decantation is a simple method used to separate a mixture of a liquid and solid by pouring off the liquid while leaving behind the sediment or solid particles that have settled at the bottom of the container. It is often used for separating mixtures with larger particles that do not pass through a filter.
