Abstract
Process for the leaching of granulated materials, such as fine minerals, pre and intermediate steel products, dust from the extraction of minerals and fluid powders, preferably from residues of calcined pyrites in chlorine or sulfatant form, for the purpose of extracting the content of gold and other non-ferrous materials according to the filtration process, characterized in that the layer of granulated material, before leaching, and in stages, is first partially oxidized with air and then with chlorine, preferably in a mixture with steam and for the leaching is carried out using a washing solution adjusted to a defined content of free chlorine, preferably 0.1 - 0.4 g/l.
