True. In mixtures, the elements or compounds are not chemically combined together, they still retain their own properties. We can make use of this and separate the constitution elements by simple physical methods.
For example, in salt water, the water compund have a property that it can boil to vapor easily, but not for the salt, therefore we can use evaporation to separate salt from water.
Some other physical methods may include distillation, crystallization, chromatography etc.
