Solid-Solid Mixtures

• Magnetic Attraction


  • magnets can be used to separate magnetic solids from non-magnetic solids
• Sieving


  • used to separate solids with different particle sizes
• Using Suitable Solvents


  • used to separate solid-solid mixtures in which only one of the solids is soluble in the solvent
• Sublimation


  • used to separate a substance that changes from the solid to gaseous state directly
  • the solid sublimes into a gas and moves away from the mixture, the gas will change back into a solid (sublimate) when it deposits on a cool surface. The sublimate is collected by scraping it off the cool surface
