The metal emission data caused by the storage of waste rock, tailings and slags referred to the leaching experiment results. The Chinese process-based LCI database provided data support for the background inventory. 火法冶炼和精炼阶段的资源消耗、原材料投入、能源消耗、污染物排放和废物处理数据参考了中国最大的镍金属生产基地甘肃公布的企业运营数据，该基地贡献了中国 80% 以上的电解镍产量。废石、尾矿和废渣贮存造成的金属排放数据参考了浸出实验结果。中国基于工艺的 LCI 数据库为背景清单提供了数据支持。 31 2018 In LEM, nickel and cobalt could be dissolved in a sulfate base in several atmospheric and pressure leaching tanks after the grinding process. The copper specimen in this study retained the leaching tailing as the by product. The leaching solution was subsequently placed in an electrodeposition tank to purify the nickel metal. The raw material production, energy generation and transportation of each unit process of the three stages were incorporated in the system boundary as background processes. 在精炼阶段，采用了中国工业化应用的两种主流技术（即磨浮电解法（GFEM）和浸出电积法（LEM）），将镍锍精炼成高纯度的金属镍。在 LEM 中，镍和钴可在研磨过程后通过几个常压和加压浸出槽溶解在硫酸盐碱液中。本研究中的铜试样保留了浸出尾渣作为副产品。浸出液随后被放入电沉积槽，以提纯镍金属。三个阶段中每个单元过程的原材料生产、能源生成和运输都作为背景过程纳入了系统边界。 The electrolytic nickel production process described is intended for the creation of battery-grade primary nickel with a purity of 99.9% nickel content. This high-purity nickel is especially suited for the manufacturing of batteries, where material quality is critical for performance and longevity. The leaching electrowinning method ensures that the nickel extracted from the nickel-copper-cobalt ore in Xinjiang Province meets the stringent requirements necessary for use in advanced battery technology, such as lithium-ion batteries for electric vehicles and portable electronics. 所描述的电解镍生产过程旨在生产含镍99.9%的电池级一级镍。这种高纯度的镍特别适用于电池制造，其中材料质量对性能和寿命至关重要。浸出电解法确保从甘肃省镍钴矿提取的镍满足用于先进电池技术的严格要求，如用于电动汽车和便携式电子设备的锂离子电池。 QQyBbuLTRoLXP9x1V2GcgGpxnPd.png Unit process, single operation None 无 None 无 None 无 None 无 None 无 Bai, Y. et al.

Strategies for improving the environmental performance of nickel production in China: Insight into a life cycle assessment. Journal of Environmental Management 312, 114949 (2022). When utilizing this data for Life Cycle Assessment (LCA), attention should be directed towards the geographic specificity of the process, as this data pertains to nickel extraction from an ore located in Xinjiang Province, China. Therefore, the environmental impacts associated with this dataset should not be generalised to nickel production in other regions without proper regionalization consideration. Users should also note any assumptions made in the extraction and processing stages and ensure that these assumptions are consistent with the scope of their LCA study. Special attention should be given to the treatment of outputs, particularly with regard to recycling and waste management practices, to accurately reflect the potential environmental benefits and burdens. 在使用此数据进行生命周期评估（LCA）时，应注意过程的地理特殊性，因为这些数据涉及中国新疆省矿石中的镍提取。因此，与此数据集相关的环境影响不应在没有适当区域化考虑的情况下泛化到其他地区的镍生产。用户还应注意在提取和处理阶段所做的任何假设，并确保这些假设与其LCA研究的范围一致。特别要注意产出的处理，特别是关于回收和废物管理实践，以准确反映潜在的环境利益和负担。 All major raw materials and all the essential energy is included. 所有主要原材料和基本能源都包括在内。 Inventory: The internal review was done by several iteration steps concerning raw data validation, raw data documentation, representativity, completeness and consistency of modelling with regard to ISO 14040 and 14044. 清单： 内部审查通过几个迭代步骤完成，涉及原始数据验证、原始数据记录、代表性、完整性、与 ISO 14040 和 14044 有关的建模的一致性。 Tiangong LCI Data Working Group 天工LCI数据工作小组 Sun Xin, xs389@cornell.edu 孙鑫, xs389@cornell.edu xs389@cornell.edu xs389@cornell.edu 2024-04-19T18:45:56+08:00 2024-04-20T14:26:30.544466+08:00 00.01.005 https://lcadata.tiangong.world/showProcess.xhtml?uuid=22a556dc-9ece-461c-820a-57ca3d3c3b96&version=01.00.000&stock=TianGong Tiangong LCI Data Working Group 天工LCI数据工作小组 Free of charge for all users and uses water Input 2190.0 2190.0 Measured Sodium dodecyl sulfate Input 0.37 0.37 Measured unspecified Input 0.00398 0.00398 Measured Nickel matte Input 1410.0 1410.0 Measured sodium carbonate Input 730.0 730.0 Measured Sulfuric acid Input 230.0 230.0 Measured Extraction agent,extractant Input 0.29 0.29 Measured Naphtha Input 5.11 5.11 Measured Activated coke Input 3.54 3.54 Measured sodium hydroxide Input 50.0 50.0 Measured Chemicals (unspecified) Input 1.26 1.26 Measured transport in t*km Input 123.9 123.9 Measured Electricity Input 12720.78 12720.78 Measured sulphuric acid Output 0.018949999999999998 0.018949999999999998 Measured hydrogen sulfide Output 0.00059 0.00059 Measured chlorine Output 3e-05 3e-05 Measured chemical oxygen demand Output 0.41 0.41 Measured Suspended solids, unspecified Output 0.0463 0.0463 Measured ammonia Output 0.00752 0.00752 Measured sulfide Output 5.4229999999999994e-05 5.4229999999999994e-05 Measured decane Output 0.0007700000000000001 0.0007700000000000001 Measured fluoride Output 0.00231 0.00231 Measured phosphorus, total Output 0.00085 0.00085 Measured nitrogen, total (excluding N2) Output 0.05024 0.05024 Measured copper Output 0.0015400000000000001 0.0015400000000000001 Measured nickel Output 0.0016200000000000001 0.0016200000000000001 Measured lead Output 0.00093 0.00093 Measured cadmium Output 0.00023 0.00023 Measured waste water - untreated Output 8890.0 8890.0 Measured municipal solid waste deposition Output 1.81 1.81 Measured hazardous waste (unspecified) Output 0.25 0.25 Measured Nickel metal (＞99.9% Ni) Output 1000.0 1000.0 Measured
