| Abstract: | In order to extract nickel and cobalt more effectively,the leaching conditions with HCl at atmospheric pressure are studied.The optimal conditions are that the particle size of laterite is-0.15 mm,initial hydrochloric acid concentration is 8 mol/L,reaction temperature is 353 K,solid/liquid ratio is 1∶4,rotation rate is 300 r/min and the leaching time is 2 h,the results show that the dissolution yields of Ni,Co,Mn,Fe and Mg can be 93.94%,60.5%,94%,56% and 94%,respectively. |
