摘要

生命周期评估(LCA)是一种数据密集型方法,被学术界和专业人士广泛用于促进环境决策和政策制定。然而,生命周期分析的有效性可能会因缺乏高质量数据和生命周期清单中的重大数据缺口而受到影响。锂提取LCA模型是采矿业中一个突出的例子。虽然锂已经成为清洁能源转型的焦点,但过度简化的模型和来自其他行业的近似降低了投入产出数据的质量。本研究旨在通过利用第一手数据和生产统计数据来提高相关利益相关者的准确性和透明度,对澳大利亚Greenbushes的世界上最大的锂矿的采矿和加工操作进行建模。结果表明,使用本研究中模拟的锂辉石精矿在锂化合物生产中的研究结果,碳酸锂和一水氢氧化锂生产的二氧化碳当量排放量分别减少了36.8%和30.6%。此外,研究表明,在Greenbushes的新工厂(cg2)中改进研磨技术,使用高压研磨辊(HPGR)将锂辉石生产的总体全球变暖潜在影响类别降低了17.3%。重要的是要注意,在加工厂中,碳足迹的最大贡献者是电力使用,而在采矿作业中,爆破是主要贡献者。

Constructing a life cycle inventory of Spodumene concentrate production: Greenbushes case, Western Australia
Life cycle assessment (LCA) is a data-intensive method widely used by academics and professionals to facilitate environmental decision-making and policy formulation. However, LCA's effectiveness can be compromised by the lack of high-quality data and significant data gaps in the life cycle inventory such as for the LCA model of lithium extraction in the mining industry. While lithium has become the focal point in the clean energy transition, oversimplified models and approximations from other sectors have diminished the quality of input and output data. This research aims to model the mining and processing operations in the world's largest lithium mine in Greenbushes, Australia, by utilising first-hand data and production statistics to increase the accuracy and transparency for stakeholders. The results demonstrate a 36.8% and 30.6% reduction in carbon dioxide equivalent emissions for lithium carbonate and lithium hydroxide monohydrate production, respectively, using this study's modelled Spodumene concentrate compared to previous studies for lithium compound production. Additionally, the study reveals that improved grinding technologies in the newer plant (CGP2) of Greenbushes have reduced the overall global warming potential impact category of Spodumene production by 17.3% using high-pressure grinding rolls (HPGR). It is crucial to note that the highest contributor to the carbon footprint in the processing plant is electricity usage, while in mining operations, blasting is the primary contributor.

期刊介绍: The Journal of Cleaner Production is an international, transdisciplinary journal that addresses and discusses theoretical and practical Cleaner Production, Environmental, and Sustainability issues. It aims to help societies become more sustainable by focusing on the concept of 'Cleaner Production', which aims at preventing waste production and increasing efficiencies in energy, water, resources, and human capital use. The journal serves as a platform for corporations, governments, education institutions, regions, and societies to engage in discussions and research related to Cleaner Production, environmental, and sustainability practices.
