EQ: What are the different methods of physical separation? SEPARATION OF MATTER NOTES.

Mixture separation!  Since mixtures are PHYSICAL combinations of pure substances, they can be separated by PHYSICAL means!  Some of the properties used.

SEPARATION METHODS FOR MIXTURES. The key is to find a property that one part of the mixture does have but the other doesn't. This relies on their physical.

Ways to Separate Mixtures

Separation Processes. Separation processes are used to separate mixtures. Filtration, evaporation, decantation and sedimentation are all separation processes.

Separation Methods. Types of Solutions & Mixtures Solution: A homogeneous mixture of two or more compounds where a solute has dissolved in a solvent Solution:

Presentation transcript:

2.3 Separating Mixtures (Physically) Mechanical Means of Separation vs. Non - Mechanical Means of Separation Using gravity, contact forces, motion… Using heat, magnetism, electricity, dissolving the mixture’s components… Picking, filtering, shaking, spinning, pouring Dissolving, boiling, melting,

Mechanical Means of Separation Density Separation Decanting: Pouring of a liquid, leaving a sediment behind Filtration: The mixture is poured into a folded piece of a filter paper in a funnel

Mechanical Means of Separation Density Separation Centrifugation: Spinning of a mixture enhances density separation

NON - Mechanical Means of Separation Chromatography Separates the substances in a solution

NON - Mechanical Means of Separation Chromatography distillation Separates the substances in a solution Separates the substances in a solution based on their different boiling points or vapour pressures

NON - Mechanical Means of Separation Froth Flotation Separates minerals (e.g. copper compounds) from a mixture of minerals in an ore (also for wastewater treatment, paper recycling)
