Abstract

Provided is a production method for efficiently obtaining a cobalt powder by means of a process which increases the reduction reaction efficiency during the production of the cobalt powder from a solution that contains a sulfuric acid cobalt ammine complex. A method for producing a seed crystal of a cobalt powder, which is characterized by sequentially performing: a complexing step for obtaining a solution containing a sulfuric acid cobalt ammine complex by adding ammonia and/or a solution of an ammonia compound into a cobalt sulfate solution; a mixing step for obtaining mixed slurry by adding a solid material into the solution containing a sulfuric acid cobalt ammine complex obtained in the complexing step; a reduction/deposition step for obtaining a cobalt powder slurry containing a cobalt deposit, in which the cobalt component is deposited, as a cobalt powder, on the solid material surface, by introducing the mixed slurry obtained in the mixing step into a reactor and reducing cobalt contained in the mixed slurry by blowing a hydrogen gas into the reactor; and a solid-liquid separation step for obtaining the cobalt deposit and the liquid after the reduction by subjecting the cobalt powder slurry obtained in the reduction/deposition step to solid-liquid separation.
