First you can use a magnet to get out the iron filings.

Second you could possibly separate the magnesium sulphate from fine sand and zinc powder by using a filter

And finally, Magnesium sulphate dissolves in water while zinc powder is insoluble, so you could use that.

silicon dioxide(sand) is insoluble in both water and dilute acid.Zincis insoluble in water,but reacts with acid to form a salt solution and hydrogen . sodium hydrogencarbonate solution collects in a beaker under the filter funnel.Pour the mixture through the filter funnel
