i did this in a lab using methods of solution, filtration and evaporation : add dilute sulphuric acid to the solid/solid mixture ..heat on a Bunsen burner till bubbles appear then filter the solution, collect the filtrate in an evaporating dish and heat on a Bunsen burner until most the water evaporates or half the filtrate has evaporated .....remove the dish from the burner and leave it on a flat undisturbed surface for 48hrs to allow crystallization.
