Treatment method of high-iron material containing nickel-cobalt-manganese hydroxide
The invention discloses a treatment method of a high-iron material containing nickel-cobalt-manganese hydroxide. The treatment method comprises the following steps of: S1, preparing the high-iron material containing nickel-cobalt-manganese hydroxide into slurry; S2, injecting a sulfuric acid solution to dissolve the slurry; S3, adding sodium hypochlorite; S4, adding a sodium hydroxide solution; and S5, carrying out solid-liquid separation, wherein the filtrate is a nickel-cobalt-manganese sulfate raw material. The method has the advantages that: 1, the process is simple and convenient, the treatment period is about 1 ton/day, the treatment process is short, the treatment technical difficulty is low, and the method is suitable for being popularized and used in general nickel-cobalt-manganese hydroxide manufacturing enterprises; 2, the treatment equipment is simple, the use requirements can be met only by using a small PP material dissolving kettle, a filter press and a matched acid-basestorage tank, and the field applicability is high; 3, the treatment cost is about 12000yuan/ton in terms of cobalt, and the treatment cost is low; and 4, oil intake is not involved, and impurities capable of influencing the production and quality of a ternary precursor cannot be introduced into the system.
本发明公开了一种含镍钴锰氢氧化物高铁料处理方法，包括以下步骤：S1、将含镍钴锰氢氧化物高铁料制成浆料；S2、注入硫酸溶液，使浆料溶解；S3、加入次氯酸钠；S4、加入氢氧化钠溶液；S5、固液分离，滤液即为镍钴锰硫酸盐原料。其优点是：1、该方法工艺简便，处理周期约1吨/天，处理流程短，处理技术难度低，适合一般镍钴锰氢氧化物制造企业普及使用。2、处理设备简单，仅使用小型的PP材质溶解釜、压滤机和配套的酸碱储罐即可满足使用要求，场地适用性强。3、处理成本折合钴计约1.2万元/吨，处理成本低。4、不涉及油份摄入，不会向体系中引入能够影响三元前驱体生产和质量的杂质。
