obtaining dissolved salt from a salt solution

evaporation

separating grains from stalks after harvesting

threshing

separating iron filings from sand using a magnet

magnetic separation

separating flour from larger particles using a mesh

sieving

separating wheat grains from chaff using moving air

winnowing

a mixture of pebbles and sand needs to be separated

sieving

recovering salt from salt water by removing the water

evaporation

removing small stones from a mixture of rice and stones

handpicking

separating lighter chaff from heavier grains using moving air

winnowing

separating oil from water because they form separate layers

separating a liquid mixture by boiling and then condensing the vapor

evaporation

separating large particles from smaller particles using a mesh screen

filtration/sedimentation

separating and collecting water from salt water by boiling and condensation

evaporation

separating visible pieces of unwanted material from beans by picking them out

handpicking

separating insoluble solid particles from water using a filter or allowing them to settle
