A method for extracting nickel and/or cobalt, comprising a process of heap leaching and a process of atmospheric warming, stirring and leaching, characterized in that the limonite-type ore is leached by atmospheric warming and stirring, while the serpentine-type ore is leached by heap leaching. According to the invention, different leaching processes are employed for the serpentine-type ore and the limonite-type ore in the laterite-nickel ore, respectively, the serpentine-type ore is leached by a process of heap leaching to obtain a faster leaching speed, and the limonite-type ore is leached by a process of atmospheric warming and stirring, thus the problems of extremely low heap leaching speed and long leaching period are avoided. |
