Belonging to the metallurgical field, the invention discloses a method for enhancing the continuous discharge performance of natural discharge manganese powder. The specific steps include: taking continuous discharge unqualified natural discharge manganese sand as the raw material, subjecting the natural discharge manganese sand to magnetic separation, then conducting powdering to obtain natural discharge manganese powder, and using a permanent magnetic separator with a magnetic field intensity of 5000-8000 Gs to perform dry separation at a rotation speed of 20-40r/min. Natural discharge manganese powder is sorted under different rotation speeds and different magnetic field intensities, and the continuous discharge time of natural discharge manganese powder can be improved to different extents, thereby prolonging the continuous discharge time of batteries and improving the battery use performance. The treatment method is very simple and low in cost, and has strong operability. The method not only improves the resource utilization ratio of natural discharge manganese powder, but also brings good economic benefits for enterprises.
