Apparatus for heating copper (II) oxide and dilute sulfuric acid. When the acid is hot enough (just before it starts to boil), use a spatula to add small portions of copper (II) oxide to the beaker. Stir the mixture gently for up to half a minute after each addition. (When adding the solid to the beaker, take care to avoid knocking the beaker.)

Sulfuric acid accelerated the reaction rate of each stage by generating catalytic nitric acid; copper oxide reduced the number of reaction stages into three via surface absorptions. The time and mass loss rate of different stages were determined.
In this case, the sulfuric acid reacts directly with the copper oxide. In many cases, copper needs to be oxidised to react with an acid, but in this case the copper is already oxidised. Because sulfuric acid itself is an oxidiser, copper sulfate also would have been formed if copper metal was used.

So sulfuric acid leaching takes us partway from copper oxide to a solution of copper sulfate. Copper oxide is insoluble solid, while a solution of copper sulfate is liquid. This makes it easier to convert the substance to pure copper. The solution is mixed with other chemicals that allow it to be reduced.
