. An extraction of nickel (90.3%) and cobalt (88.6%) was successfully achieved within a 300 d leaching process from the Jinchuan low grade nickel sulfide mineral ore using a column reactor at ambient temperature. Key words: column reactor; mixed mesophiles; nickel sulfide mineral; magnesia adaptation; pre-leaching  ......
