Heat the mixture in a beaker covered with an evaporating dish containing cold water. Iron (III) chloride sublimes and collects on the lower part of the evaporating dish.
Add dilute sulphuric (II) acid// hydrochloric acid//Nitric (V) acid to the remaining mixture and stir to dissolve copper (II) oxide. Filter to obtain lead(II) sulphate as a residue. Dry the residue between filter papers.
