The list of critical minerals from the USGS gives 50 elements that can be dissolved in wateras ions. Understanding critical minerals in solution is key to modeling processes related to ore formation, methods of ore treatment, mineral mobility, remediation of mine drainage, water quality, sustainable use of water resources, and more. However, existing thermodynamic properties for critical mineral solutes are woefully incomplete due to the sheer number of ways that other dissolved molecules can bind to them and produce new more complex solutes. This project will address this severe gap in thermodynamic data by developing techniques to estimate properties of these complex solutes and ultimately enhance quantitative models that facilitate “mining strategies and technologies to make better use of domestic resources” (Section 10359 of the CHIPS and Science Act 2022).This project will develop methods for estimating missing properties for 50 critical minerals and 75 ligands, and the nearly 30,000 possible complexes that can result. Thermodynamic estimates will be fully compatible with existing popular software tools for geochemical modeling. In addition, all estimation methods will be freely shared through an open-source interactive online web app called the CM-Complicator. This will enable users to make additional estimates and share their work through open-source, customizable, interactive online Jupyter notebooks. Users will be trained to make and apply estimates to geochemical models through a series of free online workshops. Tutorial and workhorse notebooks powered by the CM-Complicator will be distributed through a variety of other free online platforms that support Jupyter notebooks, including the free NSF-funded Water-Organic-Rock-Microbe (WORM) Portal online platform that has catered to students, teachers, researchers, and interested members of the general public since 2020.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

来自USGS的关键矿物清单提供了50个可以溶于Wateras离子的元素。理解解决方案中的关键矿物是建模与矿石形成，矿石处理方法，矿物流动性，矿山排水补救，水质，可持续使用水资源等相关的过程的关键。然而，由于其他溶解分子可以与它们结合并产生更复杂的太阳能，因此现有的关键矿物溶液的热力学特性非常不完整。该项目将通过开发技术来估计这些复杂太阳能的性能，并增强定量模型，最终促进“采矿策略和技术更好地利用家庭资源”（第202222222222222222222222年估算505年的遗漏的方法，并为505卢比估算505 lig and and 75 lig and nosge and and Socients and 75 ligig and，该项目将在热力学数据中解决热力学数据中的这一严重差距。热力学估计将与现有的用于地球化学建模的流行软件工具完全兼容。此外，所有估计方法都将通过称为CM-Complericator的开源交互式在线Web应用程序免费共享。这将使用户能够通过开源，可自定义的交互式在线jupyter笔记本进行额外的估计并分享其工作。将通过一系列免费的在线研讨会对用户进行培训，以对地球化学模型进行估算。由CM兼职器提供支持的教程和主力笔记本将通过支持Jupyter笔记本的许多其他免费在线平台分发通过使用基金会的知识分子和更广泛影响的评论标准来通过评估来支持。
