| 数据集使用建议 | 在使用此数据进行生命周期评估时，应特别注意数据的区域特异性，因为该过程基于新疆省的矿石提取。用户必须考虑过程的技术适用性，如所使用的湿法冶金方法，并确保其与系统边界内的其他过程保持一致。还应注意是否包括再循环活动，特别是如果评估范围内考虑了二次材料（回收钴）。 |
| 产品或过程的技术目的 | 该数据集代表电池级硫酸钴的生产，电池级硫酸钴常用于制造锂离子电池，这些电池广泛用于电动车辆、便携式电子产品和能量存储系统。硫酸钴通过湿法冶金工艺从位于新疆省的镍铜钴矿中生产。 |

| 关于数据集的一般性意见 | 此处使用了中国钴的主要产地新疆某企业在矿石开采和选矿阶段的实际操作数据。钴精炼阶段的数据来自实验。精炼数据采用了中国东南部一家钴精炼厂 2019 年的年度运行数据。该公司是中国五大钴精炼厂之一。本研究选择的技术是湿法冶金精炼，这与所有五个项目一致。该技术作为国际主流炼钴技术已在多篇论文中提及。中国基于工艺的生命周期清单数据库提供了二级数据支持，以确保与中国现状保持一致。一些化学品（如 Z-200、O-乙基二硫代碳酸钾、羧甲基纤维素、黄原酸丁酯、气浮丁胺、P204 和 P507）的生产数据不可用。中国的现状（如废物处理、运输和能源）被用来调整欧洲的数据，以减少欧洲的区域化效应。 |

| 技术说明，包括后台系统 | 系统边界被描述为硫酸钴生产过程中的所有活动。"从摇篮到终点 "生命周期评估研究包括从矿石开采到选矿、初级提取和精炼过程的所有相关生命周期阶段。所选矿址位于中国新疆省，是一个钴含量为 0.04% 的镍铜钴矿。钴矿石经过选矿工艺精选后，精矿的钴含量可达到 0.3%。采用浮选法进行三次筛选后，钴精矿的标准（即钴含量 9.69%）即可达到。钴精矿将通过精炼工艺制成各种形式的精炼钴产品。钴精炼采用湿法冶金技术，主要包括球磨、浸出、除铁、P204 萃取、P507 萃取、回萃和蒸发结晶等工序。 |
