    • A production process of a sulfide containing nickel and cobalt by adding a sulfurizing agent under pressurization into an aqueous solution of sulfuric acid containing nickel and cobalt, which is capable of recovering nickel and cobalt as a sulfide in high yield, as well as enhancing the utilization efficiency of hydrogen sulfide gas.
      A production process of a sulfide containing nickel and cobalt by adding a sulfurizing agent under pressurization into an aqueous solution of sulfuric acid containing nickel and cobalt, characterized by supplying, as the above sulfurizing agent, hydrogen sulfide gas into the vapor phase of inside of a reactor, as a major sulfurizing agent, as well as, by supplying an aqueous solution containing a sodium hydrosulfide, which is recovered by absorbing unreacted hydrogen sulfide gas, which is discharged from inside of the reactor in producing the above sulfide, with an aqueous solution of sodium hydroxide, into the liquid phase.
    • 通过在加压下将硫化剂加入到含有镍和钴的硫酸水溶液中的含有镍和钴的硫化物的生产方法,其能够以高产率回收镍和钴作为硫化物,以及提高利用率 硫化氢气体的效率。 通过在加压下将硫化剂加入到含有镍和钴的硫酸水溶液中的含镍和钴的硫化物的生产方法,其特征在于,作为上述硫化剂将硫化氢气体供入到 反应器,作为主要的硫化剂,以及通过提供含有硫氢化钠的水溶液,所述水溶液是通过吸收在反应器内部从生产上述硫化物中排出的未反应的硫化氢气体,用水溶液 的氢氧化钠进入液相。
