In order to solve the problem that low-grade nickel ores are difficult to process,renovated highly efficient bacterial strains are used to carry out biooxidation column leaching experiment,investigating the process conditions such as column grain size and injected bacterial amount.The results show that under optimal conditions,the adoption of renovated highly efficient bacterial strains B43 and D44 can obtain good text index when the oxidation leaching time is 180 d.The nickel and copper leaching rate can be 74.61 % and 70.52 % respectively.The research result can provide effective pathways for the development of similar low-grade nickel ores.
