Study on Hydrometallurgical Leaching of Ni-Mo Ore AITranslate
Abstract AITranslate
Ni-Mo ore was recovered by acid oxidation leaching and then alkaline leaching of acid residue.The results show that the leaching rates of Ni and Mo are 92% and 60% respectively,when HCl dosage is 0.52 mol per 100 g raw ore,solid oxidant N1 dosage 60% mass of raw ore,liquid-solid ratio 3∶1,leaching temperature 90 ℃ and time 2 h.The Mo leaching rate can be above 90% and its total recovery over 96%,when NaOH dosage is 45% mass of the dry residue from acid oxidation leaching,liquid-solid ratio 3∶1,leaching temperature 40~50 ℃ and time 15 min.The process has the advantages of simple process flowsheet,less energy consumption,and high recovery of Ni and Mo,and it can avoid the smoke pollution problem caused by pyrometallurgical desulphurization.
