The long-term, sustainable management of solid wastes is a major challenge in the mining industry and a priority for government regulation. The proposed research program focuses on integrating processes to repurpose mine tailings into regular mining operations in order to reduce environmental impacts. Repurposing mine wastes represents a promising approach to mitigate environmental impacts while also maximizing resource utilization and value generation from wastes. Findings are expected to improve the designs and efficiencies of processes to remove metal(loid)s of interest from mine wastes, thereby reducing the risks of environmental contamination and promoting the social acceptability of existing and developing projects.

固体废物的长期、可持续管理是采矿业的一项重大挑战，也是政府监管的优先事项。拟议的研究方案侧重于将重新调整尾矿用途的过程纳入常规采矿作业，以减少对环境的影响。重新利用矿山废物是减轻环境影响、同时最大限度地利用资源和从废物中产生价值的一种很有希望的办法。预计研究结果将改进从矿山废物中去除感兴趣的金属(固体)S的工艺的设计和效率，从而降低环境污染的风险，并提高现有和正在开发的项目的社会接受度。
