Describe a procedure to separate a mixture of salt, finely ground peppers, and pebbles?

well, i would add ingredients to a gl of water. salt will dissolve, peppers will float, and pebbles will sink to bottom. use a net-like tool to sift the pepper off of the top. Pour water and pebbles into another gl with a mesh/wire filter on top. pebbles will separate. then use a burner or heating pad to evaporate water leaving salt by itself.
