Separation techniques

I learnt about many separation techniques- filtration, crystallisation, distilation, fractional distillationa and evaporation to dryness . It also learnt about the apparatus used for the techniques.On 1p15, we had to separate a mixture of salt and sand.Darryl and I separted it by filtering the sand out by using a filter paper then we boil the filtrate until all the water to evaporated. In the experimennt, we used two kinds of separation techniques which was filtration and evaporation to dryness.
