WHAT IS FILTRATION?FILTRATION= is the process of separating mixtures through a filter. 9. MAGNETIC SEPARATION 10. WHAT IS MAGNETIC SEPARATION?Magnetic separation= is used to separate metallic substances from non-metallicsubstance. 11. WINNOWING 12. WHAT IS WINNOWING?Winnowing= is separating the chaff from the grains by wind. 13. SIEVING 14. WHAT IS SIEVING?Sieving= used for separating coarse from fine parts of loose matter. 15. EVAPORATION 16. WHAT IS EVAPORATION?Evaporation= is the process of changing liquid to gas by heating, therebyseparating solids from the liquids in the mixture. 17. WHAT IS STRAINING?Straining= pour a mainly liquid substance through a porous device or materialin order to separate out any solid matter. 18.
