【摘要】在总结四氧化三钴合成技术现状的基础上,开发了一种加压湿法合成四氧化三钴的新方法,以H2O2为氧化剂,直接从含钴溶液中氧化合成四氧化三钴,得到了粒径为0.3～0.5μm的球形四氧化三钴。与传统方法经济比较结果表明,采用新方法每吨钴可降低成本8300元。目前正在北京矿冶研究总院进行小型和扩大试验研究。更多还原

【Abstract】 Based on the summarization of synthesizing technology of Co₃O₄, a new pressure hydrometallurgical technology has been developed which synthesizes Co₃O₄ from cobalt solution directly with H₂O₂ as oxidant.The spherical Co₃O₄ has been obtained with particle size ranging from 0.3μm to 0.5μm.The comparison with traditional processes on economy suggests that the operation cost can drop 8300$ per ton.Now, lab and pilot experiments are conducting in BGRIMM.更多还原
