Indlela yokuphendula yokuphendula (i-RSM) yayisetyenziselwa ukufunda inkqubo ye-nitric achic achic yenkunkuma yenkunkuma. Injongo yolu phononongo yayikukwazisa i-CO kunye ne-mo evela kwi-solvent kwi-solvent ngohlobo lokuzicocwa kwamanzi, ukwenzela ukuba kube lula ukucocwa kwamanzi kunye nokusetyenziswa kwezixhobo zenkunkuma eqinileyo, ubushushu bendlela yokuphendula kunye nolwelo. Izinto eziphambili zokuphembelela zenziwa yindlela yokuphendula, kunye nomzekelo oquation weeparameters zenkqubo kunye ne-cobult kunye ne-molybdenum leaching zisekwe. Phantsi kweemeko ezifanelekileyo zenkqubo efunyenwe yimodeli, ireyithi yokutsiba ye-Cobaching yayingaphezulu kwe-96%, kwaye i-Molybdenum Leaching Inqanaba lingaphezulu kwe-97%. Ibonise ukuba iiparamitha zenkqubo efunyanwa yindlela yokuphendula yayichanekile kwaye ithembekile, kwaye inokusetyenziselwa ukukhokela eyona nkqubo yemveliso
