when you mix salt and water, it will produce a homogeneous mixture and you can separate it by evaporating the mixture...

As you use the word 'separating' in your question, I assume you wish to recover both the salt and the water at the end of the process. To do this you need to use a process known as distillation. Heat the solution in a flask until it boils. The water will evaporate and leave the salt behind. Pass the water vapour through a condenser (a glass tube that has a jacket of cold water surrounding it). The water vapour will condense back to liquid and drip into a container. Take care that you do not boil the flask dry or it will crack. When there is only a little liquid left in the flask, stop heating and allow the remaining water to evaporate naturally in a warm draughty place.

evaporation. Put the mixture over the flame and the water will evaporate leaving behind solid crystalline salt as residue.
