By heating copper sulfate is decomposed in copper(II) oxide and sulfur trioxide; by reduction of the copper oxide with hydrogen copper is obtained.
There are various method for manufacturing copper sulphate commercially. it can be manufactured by the action of sulphuric acid on copper in the presence of air/O2. reacting copper with dilute sulphuric acid in the presence of strong oxidising agents like HNO3. By converting copper into copper oxide and dissolution of oxide into dilute sulphuric acid. once we get liquid copper sulphate solution from reaction then the normal operations are filtration , concentration, crystallisation, separation & drying of crystals
No, it cannot be prepared by this method under normal conditions. For preparing copper sulphate, copper should be added to the sulphate salt of a metal which is less reactive than copper like Mercury, silver and gold

Well, you need to get a beaker and add water.Then add the powdered chalk and add copper sulphate to the beaker.Then get a conical flask with a funnel and get some filter paper and fold it into a funnel and place it the funnel in the conical flask then mix your solution with a stiring rod and pour down funnel .What you should end up with is copper sulphate with the water in the conical flask and the chalk mix in the filter paper.
chromatography?
none
The scrape orwasted copper pieces are boiled in sulphuric acid in open air then mixture is worked up with water.
Evaporation + crystallization
For the best results reaction should take place in the slightly acidic solution (pH around 4-5), correct pH is obtained by addition of acetic acid.
screening
Pouring off can only separate solids or liquids with a different density than the solution.
