摘要

可持续能源解决方案和电气化正在推动对关键矿物需求的增长。遗憾的是,目前的矿物加工技术需要消耗大量资源,使用大量有害化学品,而且需要在集中的设施中进行,以实现规模经济。现有技术的这些方面与推动关键矿物需求增长的可持续发展目标相悖。在这里,我们认为膜技术的小足迹和模块化特性使其能够很好地解决矿石和盐水中浓度下降的问题、循环利用中遇到的给料浓度变化问题以及与当前分离过程相关的环境问题;因此,膜技术为加强有弹性的关键矿物供应链提供了新的可持续发展途径。创建循环经济的成功取决于克服从分子到基础设施范围内的各种障碍。因此,要解决这些挑战,需要跨学科研究的融合,而不是孤立的创新。

Critical Mineral Separations: Opportunities for Membrane Materials and Processes to Advance Sustainable Economies and Secure Supplies.
Sustainable energy solutions and electrification are driving increased demand for critical minerals. Unfortunately, current mineral processing techniques are resource intensive, use large quantities of hazardous chemicals, and occur at centralized facilities to realize economies of scale. These aspects of existing technologies are at odds with the sustainability goals driving increased demand for critical minerals. Here, we argue that the small footprint and modular nature of membrane technologies position them well to address declining concentrations in ores and brines, the variable feed concentrations encountered in recycling, and the environmental issues associated with current separation processes; thus, membrane technologies provide new sustainable pathways to strengthening resilient critical mineral supply chains. The success of creating circular economies hinges on overcoming diverse barriers across the molecular to infrastructure scales. As such, solving these challenges requires the convergence of research across disciplines rather than isolated innovations.

期刊介绍: ACS Applied Polymer Materials is an interdisciplinary journal publishing original research covering all aspects of engineering, chemistry, physics, and biology relevant to applications of polymers. The journal is devoted to reports of new and original experimental and theoretical research of an applied nature that integrates fundamental knowledge in the areas of materials, engineering, physics, bioscience, polymer science and chemistry into important polymer applications. The journal is specifically interested in work that addresses relationships among structure, processing, morphology, chemistry, properties, and function as well as work that provide insights into mechanisms critical to the performance of the polymer for applications.
