These methods typically do not involve pre-treatments to remove non-metallic components, which causes increasing reagent and energy consumption, and greenhouse gas emission during recycling. Mechanical methods exploiting differences in material properties, such as gravity, magnetic, electrostatic, can achieve pre-treatment which receive increasing attention. Amongst different mechanical methods, froth flotation utilizing surface hydrophobicity to achieve the desired separation appears to receive less attention but can be very promising to recycle a variety of e-wastes. In this work, the challenges and advances in the recovery of metals from three main e-wastes, including spent lithium-ion batteries (S-LIBs), waste printed circuit boards (WPCBs), and spent photovoltaic solar panels (S-PVs), using flotation were reviewed. The work also conducted a life cycle analysis to assess the environmental impact of flotation in recycling these e-wastes. According to TRACI standards, flotation reagents have the highest environmental impact compared to electricity and water consumption. The study suggests that flotation can serve as an effective pre-treatment operation prior to the chemical treatment to improve the overall the e-waste recycling but future research is still needed.</div></div>","PeriodicalId":21153,"journal":{"name":"Resources Conservation and Recycling","volume":null,"pages":null},"PeriodicalIF":11.2,"publicationDate":"2024-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142432917","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, few studies focus on uncovering the key determinants on the supply disruption of such ores. This study investigates the key determinants that influenced the disruption of 18 types of ores’ production from 2010 to 2022 through the combination of web crawler, AI-text classification and manual processing methods. Results show that determinants such as politics, natural disasters, strikes and protests, economy, and energy, play crucial roles. Specifically, these determinants have different impacts in different countries and therefore require different policy designs, such as environmental protection policy (in China influencing Zinc, Tungsten, Molybdenum, and Iron), banning resource export (in Indonesia influencing Nickel and Tin), domestic risks (in Democratic Republic of Congo influencing Copper and Cobalt), extreme climate disasters (in Australia—influencing Iron, Aluminum, and Gold, and in Chile—influencing Copper and Lithium), natural disaster (in South Africa—influencing Chromium, Manganese, Platinum, Gold, and Fe, and in Chile—influencing Copper and Lithium), and strike and protests (in Peru—influencing Copper, Silver, and Zinc, and in South Africa—influencing Platinum and Gold). These findings can help stakeholders better prepare their strategies to improve the overall resilience of the entire ores supply chain and facilitate the global low carbon transition. Several policy recommendations are then proposed to improve sustainable supply of key minerals.</div></div>","PeriodicalId":21153,"journal":{"name":"Resources Conservation and Recycling","volume":null,"pages":null},"PeriodicalIF":11.2,"publicationDate":"2024-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142432916","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Quantitative analyses characterizing to what extend diversification shield countries from supply disruptions remain however scarce. In this paper, we present a methodology to assess the supply risk exposure of countries in different supply diversification scenarios – business-as-usual, reshoring, friendshoring. For each scenario, the propagation of three types of upstream disruptions – supply shortage, export restriction, bilateral trade conflict – is simulated. A fragility ratio metric is introduced to quantify the potential downstream shortages caused by these disruptions. A novel friendshoring modelling approach is also proposed.
