“…Analysis. Sensitivity analysis is a key part of LCA testing the sensitivity of LCI input data, which can be calculated [17] based on the percentage adjustment rule of input and output parameters (ISO 14044, 2006;ISO 14040, 2006). A sensitivity analysis was performed by changing 5% of the material input at a time [18].…”

The steel industry is facing problems such as serious environmental pollution and high resource consumption. At the same time, it lacks effective methods to quantify potential environmental impacts. The purpose of this work is to conduct a specific environmental analysis of steelmaking production in steel plants. The ultimate goal is to discover the main pollution of steelmaking and identify potential options for improving the environment. This paper uses life cycle assessment method to carry out inventory and quantitative analysis on the environmental impact of steelmaking system. Through analysis, the hazards are divided into four major categories, which are human health, climate change, ecosystem quality, and resources. The results show that molten iron has the greatest impact on human health, followed by the greatest impact on resources. The impact of scrap steel on human health ranks third. Molten iron is a key process that affects human health, climate change, ecosystems quality, and resources. In addition, processes such as fuels, working fluids, and auxiliary materials also cause certain environmental damage, accounting for a relatively small proportion. Optimizing the utilization of scrap steel and molten iron resources and improving the utilization efficiency of resources and energy are helpful to reduce the environmental hazards of steelmaking system.

“…In addition, LCA can provide useful insights about the mining industry [18] providing guiding effort in decision-making through sustainability reporting. The knowledge of LCA has been applied to evaluate the environmental footprints of minerals and metals such as coal mining [9,10,19], gold [20], copper [21], iron [22], zinc [23], cobalt [24], lead-zinc [25,26], and other mineral industries [27]. However, minimal studies are present in the literature that assess the environmental impacts of ASM using LCA for example, sandstone mining [28], gold mining [29], mine tailings [30], and cobalt [31].…”

Artisanal and small-scale mining (ASM) is regarded as a means to enhance and uplift living standards in rural areas, often serving as the primary livelihood for local communities, however, the environmental burden associated with ASM cannot be ignored. Compared to other minerals, studies emphasizing the environmental and health impacts of kaolin mining and its beneficiation are limited. This research employed the life cycle assessment (LCA) tool to evaluate the environmental consequences and health problems associated with artisanal and small-scale kaolin mining (ASSKM) based on ReCipe 2016 Midpoint (H) and IPCC GWP 20a methods. Foreground data was collected from the mining site and the background data was accessed using the Ecoinvent v3 database. Standardized results showed a higher contribution of marine ecotoxicity, followed by human carcinogenic toxicity, freshwater ecotoxicity, and human non-carcinogenic toxicity. Contribution analysis revealed that electricity, diesel, and steel consumption contributed heavily among the above impact categories. Based on the sensitivity analysis results, the key measures to tackle environmental impacts involve improving kaolin beneficiation and mining operations. Among the health issues, musculoskeletal problems were recognized as the most affected problem encountered by miners followed by skin irritation and respiration problems however hearing loss and eye irritation showed lower scores. This study seeks the attention of stakeholders, environmentalists, policymakers, and licensing authorities, urging them to develop policies that promote environmentally sustainable practices in ASM within the region.

“…Therefore, the Ministry of Ecology and Environment of China has included lead anode slime (Waste Code 321-019-48) in the National Hazardous Waste List and strictly manages its storage and treatment [18]. To obtain the precious metals, the other elements present in LAS must be removed [19,20]. Conventional treatment of LAS involves pyrometallurgical processes and electrolytic refining.…”

Huge amounts of Au and Ag are recovered from the hazardous waste lead anode slime. The conventional extraction of precious metals from lead anode slime is based on pyrometallurgical and electrolytic processes, which are seriously conditioned by the separation of harmful elements As and Sb. In this paper, an innovative and efficient oxidation–vacuum volatilization–carbon reduction process was proposed to separate and enrich Ag and Au from lead anode slime. Before vacuum volatilization, selective oxidation of the lead anode slime was performed. Then, vacuum volatilization and vacuum carbon reduction were used to obtain a gold- and silver-rich alloy. The feasibility of the process was verified experimentally and theoretically. The effects of temperature and time on vacuum volatilization separation and reduction enrichment were investigated. The experimental results showed that the Ag content in the resulting gold- and silver-rich alloy was as high as 67.58%, Au was as high as 4287 g/t, and the efficiencies for the recovery of Ag and Au from the lead anode slime were 99.25% and 99.91%, respectively. The gold- and silver-rich alloy can be directly used to produce Ag ingots. Moreover, no gas or wastewater was discharged in this process, so Ag and Au were recovered in a sustainable and cleaner manner.
