Procedure for the exploitation of minerals and products containing heavy metal sulphides, characterized essentially because the minerals and products mentioned are subjected to the action of higher oxides of nitrogen, sulfates being oxidized to sulphates soluble in water and this solution separates the heavy metals, whereas the higher oxides are reduced to nitric oxide, from which the higher oxides are regenerated by oxidation in the gas phase with air and oxygen, thus recovering said higher oxides of nitrogen to oxidize new sulphides and verifying, in sum, the oxidation of solubilization of the sulfides without more consumption than oxygen of the air and pure oxygen.
