江西新余焙烧水浸料稀酸还原浸出及锂的深度提取：焙烧水浸料稀酸还原浸出及锂的深度提取技术数据集（2021年）

本技术其主要内容是三元锂电粉体材料经过复配盐焙烧水浸后，再经液固分离得到含锂溶液与镍钴锰固熔体渣，为了进一步提取镍钴锰金属，研究采用稀酸还原浸出工艺，提高镍钴锰金属的回收率，并回收残留锂。水浸渣按计量液固比加入自来水制浆。然后加入硫酸调节浆液的pH值，开启加热，待温度升至一定温度后，加入适量双氧水进行还原浸出。浸出完成后过滤，滤渣和滤液分别送样检测分析Co、Ni、Mn、Li。

The core of this technology involves subjecting ternary lithium-ion battery powder materials to roasting and water leaching with compound salts, followed by liquid-solid separation to obtain a lithium-containing solution and nickel-cobalt-manganese solid solution slag. To further extract nickel, cobalt and manganese metals, this study adopts a dilute acid reductive leaching process to improve the recovery rate of nickel, cobalt and manganese metals and recover residual lithium. The water leaching residue is slurried with tap water according to the measured liquid-solid ratio. Sulfuric acid is then added to adjust the pH of the slurry, and heating is initiated. Once the temperature rises to a predetermined level, an appropriate amount of hydrogen peroxide is added for reductive leaching. After the leaching is completed, filtration is performed. The filter residue and filtrate are separately sampled for detection and analysis of Co, Ni, Mn and Li.
