So non-carbonated CaO materials were examined to replace limestone in this study. It was attempt to replace limestone by used blast furnace slag, converter slag, and KR slag with high CaO content. For manufacture clinker, LSF, SM, and IM were controlled at 92, 2.5, and 1.6, respectively, and the CaCO3 replacement rate was fixed at 3%, 6%, 9%, and 12%. As using blast furnace slag, the CaCO3 replacement rate was possible up to 12%, but for converter slag and KR slag, up to 3% and 9% were possible. The burnability of clinker was better when blast furnace slag and KR slag were used. The XRD peak intensity of clinker used blast furnace slag gradually decreased as the amount of slag used increased, but when KR slag was used, the XRD peak intensity actually increased. It was presumed to be because KR slag has a high CaO content and already contains C2S, making it easier to produce clinker minerals.","PeriodicalId":20967,"journal":{"name":"Resources Recycling","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135976915","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most of industrial by-products with chlorine can affect clinker properties. In this study, the mineralogical properties of clinker as chlorine content, especially alite and belite mineral properties and burnability were examined. The burnability of clinker was better as the chlorine content increased and the best results were obtained at clinker with 2,000ppm chlorine. Free-CaO content decreased by about 37% at 2,000ppm compared to 0ppm chlorine. Alite size increased slightly as the chlorine content increased, and became smaller as IM increased. XRD peak intensity of alite increased up to 1,000ppm chlorine content under IM 1.5 and 1.7 conditions, but slightly decreased at 2,000ppm. But alite peak intensity at 2,000ppm was higher than that of 0ppm. From the above results, it was confirmed that IM and chlorine content can change the clinker mineral size and also change the XRD peak intensity.","PeriodicalId":20967,"journal":{"name":"Resources Recycling","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135976469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experiments were done by a random sequence using the design of 2-level and three repetitions with a central point. The factors and their levels were roasting temperature 1000, 1200 °C, sodium sulfate ratio in sodium salt 30, 70 %. The change in factor level did not give a statistically meaningful effect on the vanadium leaching ratio based on T-test and ANOVA with a significance level of 0.05, and the vanadium leaching ratio was between 80 and 90 % in 30 minutes. In contrast, the factors and interaction had a statistically significant effect on the aluminum leaching ratio. Higher temperature and sodium sulfate ratio produce a higher aluminum leaching ratio, whereas the interaction of factors showed the opposite. Water leaching of roasted vanadium concentrate at 1000 °C/sodium sulfate ratio of 30 % and 1200 °C/70 % resulted in 8.96 % and 0 % of aluminum leaching ratio, respectively. A regression analysis produced an aluminum leaching model equation with an R-squared of 0.9960.","PeriodicalId":20967,"journal":{"name":"Resources Recycling","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135976911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the conventional process has faced environmental problems due to gas and wastewater generation, high-energy consumption, and the use of strong acids/alkalis for an extended period of time. An innovative recycling technology exploiting the mechanochemical process is proposed to overcome the drawbacks of the conventional process and improve the metal recovery from spent batteries. In general, the unique mechanism by mechanochemical reaction enables metal extraction with non-hazardous materials and minimal use of solvents at ambient temperature. This emerging technique can be combined with hydrometallurgical processes and offers potential for reagent regeneration. This article reviews different recycling technologies for spent lithium-ion battery cathode materials, particularly the mechanochemical process, to achieve circular economy in spent battery recycling and enhance lithium recovery.","PeriodicalId":20967,"journal":{"name":"Resources Recycling","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135976912","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to respond more accurately and quickly to greenhouse gas regulations, including the domestic emissions trading system, it is necessary to establish a system for accurately identifying greenhouse gas emission sources and calculating emissions for each lime manufacturing process. In this study, in order for limestone processing companies to effectively respond to the domestic greenhouse gas emissions trading system, the operation method, input raw materials, and fuel differences for each type of limestone kiln were identified through field surveys, and the greenhouse gas emission intensity was analyzed As a results, it was confirmed that greenhouse gas emissions were reduced when using a Parallel flow regenerative kiln compared to an improved shaft kiln even when the same amount of limestone was used.","PeriodicalId":20967,"journal":{"name":"Resources Recycling","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135976916","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
