: CPG (CO 2 Plume Geothermal) has recently emerged as a promising technology to combine the extraction of geothermal energy with underground CO 2 storage, thus achieving double positive results. The idea is to inject CO 2 in its supercritical form to create a plume and replace the reservoir brine, which is continuously circulated to transfer heat from the reservoir to surface facilities. Apart from the positive aspects of this technology, including the reduced energy to inject and lift the working fluid as well as its enhanced mobility in the reservoir and reduced environmental footprint, there are also negative issues that must be handled by adequately studying the geological field/reservoir and appropriately designing the production system. In this work, we present a finite volume numerical simulation that can study a geothermal reservoir from its geological origin to the dynamic simulation of CO 2 injection and estimate the geothermal energy extraction. It is shown that the system performance is strongly related to the selected schedule, and optimizing it in conjunction with the related cost is of the utmost importance for the Final Investment Decision to be taken and for the viability of such multipurpose projects under a sustainable future.
:CO2 烟羽地热（CPG）是最近出现的一种很有前途的技术，它将提取地热能与地下 CO2 储存结合起来，从而取得双重积极效果。其原理是注入超临界形式的二氧 化碳，形成烟羽，取代储层盐水，盐水不断循环，将热量从储层传递到地面设施。除了这项技术的积极方面（包括减少注入和提升工作流体的能量、提高其在储层中的流动性以及减少对环境的影响），还存在一些消极问题，必须通过充分研究地质场/储层并适当设计生产系统来解决。在这项工作中，我们提出了一种有限体积数值模拟方法，可以研究地热储层从地质起源到二氧化碳注入的动态模拟，并估算地热能提取量。结果表明，系统性能与所选时间表密切相关，结合相关成本优化时间表对于做出最终投资决策以及此类多用途项目在可持续未来的可行性至关重要。

: Acid sulfate waters originated from acid rock drainage (ARD), affecting the La Silva stream (El Bierzo, Spain), present anomalously high values of rare earth elements and yttrium (REY). These REY are maintained dissolved along the water stream as sulfate ions forming complexes like REYSO 4+ and REY(SO 4 ) 2 − . Negatively charged REY complexes seem to have an affinity for iron precipitates found along the La Silva stream and its tributaries since their surface is positively charged at this low pH. The presence of iron-oxidizing bacteria in iron precipitates addresses the possibility of their implication in this REY immobilization and its potential use in (bio)remediation and strategic metal industry applications.
:源于酸性岩石排水（ARD）的酸性硫酸盐水影响了拉席尔瓦溪流（西班牙埃尔比耶索），呈现出异常高的稀土元素和钇（REY）含量。这些稀土元素以硫酸根离子的形式溶解在水流中，形成 REYSO 4+ 和 REY(SO 4 ) 2 - 等络合物。带负电荷的 REY 复合物似乎与拉席尔瓦河及其支流中的铁沉淀物有亲和力，因为在这种低 pH 值条件下，它们的表面带正电荷。铁沉淀物中存在铁氧化细菌，这说明它们有可能参与这种 REY 固定化，并有可能将其用于（生物）修复和战略性金属工业应用。

: In this work, electrodialysis (ED) and electro-electrodialysis (EED) were investigated as technologies for the recovery of Sb from wastes and effluents generated during the pyrometallurgical processing of copper sulfide minerals and the hydrometallurgical treatment of low-copper-content mixed minerals. This work addresses the challenge of applying electrochemical methods for recovering these valuable materials and recycling highly concentrated acid solutions used in the latter separation stages of the electrorefining process. The electrochemical characterization of the solutions was conducted, and the electrodeposition of Sb and Bi was performed in electrochemical cells. Also, the implementation of membrane processes in the recovery of such materials was investigated.
