The invention relates to a method for recovering copper, Mo, Fe, Pt, Au, Ag, Zn, Ni, Sn, Co, U, Re, Ge, Se, rare earth metals and any other metal from the Periodic Table of the Elements present in the slag content, obtained from the slag produced by copper smelting such as in the fusion and conversion of slag, from reverberatory furnaces, and especially the Teniente converter and Pierce-Smith converter, the slag from refining, anodic slag, the oxidized slag and/or any other slag or molten metal that produces slag, wherein the method comprises at least one of the following steps : a) subjecting the slag to cascading stages separated by phases, which prepares the slag while copper is recovered, wherein each stage comprises at least one stage comprising at least one of the crushing, magnetic separation and/or milling methods and wherein the number of stages per phase depends on operational considerations; b) recovering the copper, molybdenum and other metals present in the slag by means of a reactor into which the slag is fed to obtain a concentrated solution including mainly copper, molybdenum and iron.
