本文研究了电炉还原贫化处理液态转炉渣提钴的新工艺所产出的钴锍的矿物组成。在研究缓冷钴锍的矿物组成和钴的分布规律的基础上,判断了冶炼过程中的物化反应。运用相关系指出了适当控制贫化条件可以获得含Fe°22~25%,S20~22%的金属化钴锍,缓冷结晶后钴90%左右以Co-Ni-Fe合金形式存在。从工艺矿物角度论证了我院提出的转炉渣提钴采用电炉贫化一金属化钴锍缓冷——选矿富集—加压氧化酸浸—P_(204)萃取分离镍钴——氢还原提取金属钴粉流程的相对合理性。
In this paper, the mineral composition of cobalt sulfonium produced by the new process of cobalt reduction and depletion in liquid converter slag was studied. On the basis of studying the mineral composition of slow cooling cobalt sulfonium and the distribution of cobalt, the physicochemical reaction in the smelting process was judged. It is pointed out that proper control of the depletion conditions can be used to obtain metallic cobalt sulfonates containing 22-25% Fe and S20-22% Fe, and about 90% cobalt is present as Co-Ni-Fe alloy after slow cooling crystallization. From the perspective of process and mineralization, the converter slag cobalt extraction proposed by our institute was characterized by slow cooling of the electric furnace-cobalt-sulfides-enrichment-pressurized oxidation acid leaching-P_ (204) extraction and nickel-cobalt- The Relative Rationality of Metallic Cobalt Powder Process.
