Principle of wet copper smelting

The chemical equation of copper hydrometallurgy is:

1.CuO+H2SO4 == CuSO4+H2O Basic reaction type: metathesis reaction.

2.CuSO4+Fe == Cu+FeSO4 Basic reaction type: displacement reaction.

Brief introduction of copper hydrometallurgy: copper hydrometallurgy is to convert copper in copper mine into soluble copper sulfate with sulfuric acid, and then put iron into copper sulfate solution to replace copper. This method is called wet copper smelting. The technology of copper hydrometallurgy was invented by ancient people in China, and its principle is to make metal by displacement reaction. China is the first country in the world to adopt wet copper smelting.
