SEPARATING MIXTURES.

What everyday items can you think of that need to be separated and what are the processes used to complete these separations?

SIEVING…..

DECANTING…. water supply-upper layer taken for use after sedimentation

MAGNETIC SEPARATION… SEPARATING ORES FROM MINED EARTH.

GRAVITY SEPARATION… SEPARATING ORES GOLD PANNING

EVAPORATION…. SALT FROM SEA WATER…

FILTRATION…. DIESEL FILTRATION AIR FILTRATION HEINEMANN INTERACTIVE P76 water supply cleaned of impurities, wine making-remove skin

Separating Techniques Use pages 75 & 76 in the text book to fill in the table Technique NameDefinitionExamples in real life SievingUsed to separate small chunks of ore from larger ones. Sifting flour, separating pasta from water when cooking DecantingWater supply-upper layer taken for use after sedimentation Sand in water Magnetic separation SEPARATING ORES FROM MINED EARTH. At the tip Gravity separationWhen you separate materials because one is heavier than the other Gold digging Evaporation FiltrationSeparate small particles from a liquid Now turn to page 82. Answer in sentences Q1, 2 and 4 (turn back to p 75/6 or the table above)

DISTILLATION…. make perfumes from plant materials, petrol oil

CHROMATOGRAPHY…. Separate colours in food dyes, pesticides in food

Centrifuging…. oil Wet clothes Blood products

Uses for Chromatography. Paints, inks dyes and food colourings are often mixtures of substances that have different colours. These can be separated using paper chromatography. Can detect very small amounts of harmful pesticides in foods Detect drugs in urine Separate complex chemicals found in cells of living things Check composition and purity of chemicals used in industry Used to make and purify chemicals by manufacturers of medicines.
