Abstract
Chemical process for the use of metallic pyrites and sulfides, characterized in that the sulphides or ground pyrites are subjected to the action of an aqueous solution of nitric acid until the oxidation of the sulfide is completed, followed by the mixing of gaseous nitric oxide, coming from the reduction of the acid nitric, with air, for new oxidation of that and later dissolution in water, regenerating in it the nitric acid.
