Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT The past decade has witnessed a burgeoning demand of metals for global industrial development and infrastructure. Meanwhile, the depletion of mineral resources and the environmental damage caused by wastewater discharges pose significant threats to both economic and ecological sustainability. Fortunately, metal‐containing wastewaters also hold

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Chlorination roasting has emerged as a promising pyrometallurgical strategy for the selective recovery of lithium from spent lithium‐ion batteries (LIBs). In this study, a natural roasting agent, seawater‐derived chlorides, was employed to selectively extract lithium from spent LiNi0.5Co0.2Mn0.3O2 (NCM523) cathode. MgCl2·6H2O, a main component

Achieving Transboundary Water Security Through Water Innovations: A Framework and Cases
World Water Policy, Volume 12, Issue 1, February 2026.ABSTRACT Alternative sources of freshwater, provided by various innovations, have long been available to countries facing acute water stress. We hypothesize that avoiding and/or resolving conflict with neighbors—caused by the uncertainty of continued access to shared surface water and groundwater sources—is another driver of innovation adoption ...

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Deep eutectic solvents (DESs) have displayed a significant potential in green recycling of spent lithium‐ion batteries (LIBs) cathode materials. In this study, we proposed a computational screening strategy based on the binding energy and hydrogen bonding performance via density functional theory and molecular dynamic calculation, achieving a ...

Gongye shui chuli, 2008 选矿废水循环利用的关键是回用废水不影响选矿指标。为解决四川会东铅锌矿选矿废水循环利用的问题，分别研究了经自然降解、混凝沉降、Na2SO3处理及混凝沉降—活性炭吸附等方法对选矿废水进行处理后回用的方案，研究结果表明，混凝沉降—活性炭吸附处理工艺可有效地去除废水中的重金属离子及有机污染物。处理后的选矿废水回用不会影响选矿产品质量，可实现选矿厂废水的零排放，工业应用结果良好。

Gongye shui chuli, 2004 介绍了保定肉联厂废水处理及处理水回用工程设计,该厂废水采用水解酸化-气浮-SBR法处理,处理后的排水指标达到国家规定的排放标准,并且部分排水直接回用,低质低用。处理废水成本为0.55元/t,回用水成本为0.65元/t,远远低于城市自来水价格,每年节省的水费不仅可以补偿污水处理运行费用,还可创造4.5万元的经济效益。
