FIELD: metallurgy.
SUBSTANCE: invention concerns method of noble metals recovery from phosphatic ore. Method includes handling by acid solution and/or oxidant while irradiation by microwave field with noble metals conversion into solution and suspension. Before handling by acid solution and/or oxidant, beforehand ore is irradiated by microwave field and separated to magnetic, submagnetic fractions and nonmagnetic residue. Magnetic and/or submagnetic fraction(s) are handled by acid solution and/or oxidant while irradiation by microwave field with further noble materials sorption from solution and suspension by sorbate, which is burned then with receiving noble materials concentrate. Technological result is mass increasing of recovering noble metals and also additionally scandium recovery.
EFFECT: mass increasing of recovering noble metals and additionally scandium recovery.
