Filtration.
Reason: a precipitate (insoluble solid) suspended in a liquid is separated most directly by filtration (gravity or vacuum), which collects the solid and lets the liquid pass. Distillation and evaporation remove liquid but won't selectively separate the precipitate from dissolved salts; sorting is for macroscopic manual separation.
