1) If the substance has not dissolved (e.g. a mixture of sand and water) you can use filtration
2) If the substance has dissolved (e.g. a mixture of salt and water) you can use evaporation
3) If the mixture contains different colours of ink you can use chromatography
4) If the mixture contains liquids with different boiling points you can use distillation
