Only by crystalisation.To seperate,the mixture is added to warm water.Only copper sulphate dissolves in water.The solution is filtered.Chalk powder remains on filter paper.The filtrate is evaporated to get concentrated solution.On cooling the solution copper sulphate crystals are formed.

First, put the copper sulphate and chalk powder into a beaker of water, stir & dissolve the copper sulphate crystal in water.
Second, filter the solution using a filter paper & a funnel, the residue on the filter paper is the chalk powder.
Third, boil the solution over a fire till the water evaporates, copper sulphate crystals is left.

A classifier screen
Copper sulphate CRYSTALS & chalk POWDER are both dry.
THere'd be nothing to boil......

Copper sulfate dissolves in water. Chalk doesn't. Add mixture to the mixture and stir until the copper sulfate is dissolved. Pour the liquid through a filter. The chalk is in the filter, the copper sulfate has run through.
