Copper and molybdenum extraction process, comprising the steps of: molybdenum - copper concentrate ore with oxygen at a first feed solution containing copper and halide present conditions, the first pressure oxidation to produce a first copper solution and a solid residue containing molybdenum; refined copper ore in the presence of a second feed solution containing copper and oxygen and a halide, a second pressure oxidation to produce a second copper solution and a solid residue; The second solution containing copper is subjected to solvent extraction to form a copper-rich solution and a raffinate; recycling the first portion of the raffinate together with the first copper-containing solution as the second feed liquid to the first Second pressurized oxidation; recycling the second portion of the raffinate as the first feed to the first pressurized oxidation.
