This project will investigate the potential for the transformation of pyrite (iron disulphide) from mine waste (tailings) into raw materials for batteries. The research conducted will be the crucial link between the mineral processing of pyrite from tailings and subsequent battery performance. The research will build on a proof-of-concept study in which a functioning battery was produced from tailings pyrite. Although the concept has been demonstrated, an efficient processing route for pyrite in tailings for optimised battery performance has not yet been presented. Many unanswered questions remain regarding the characteristics of pyrite from tailings and their effect on battery performance after processing. The project will study pyrite-bearing waste from multiple sites (e.g., Spain/Portugal) and at different ages (fresh tailings and older tailings ponds). The aim is to establish the variability of the pyrite from a given location, the processes required for cleaning the pyrite to an acceptable purity, and the limits of that purity with respect to battery performance to identify suitable locations for future implementation. The research will consider the environmental impact of recovering pyrite from tailings at an industrial scale, through modelling and simulation.

该项目将研究将矿山废料（尾矿）中的黄铁矿（二硫化铁）转化为电池原材料的潜力。所进行的研究将成为尾矿黄铁矿选矿与后续电池性能之间的关键环节。该研究将建立在概念验证研究的基础上，其中使用尾矿黄铁矿生产功能电池。尽管这一概念已经得到论证，但尚未提出一种有效处理尾矿中黄铁矿以优化电池性能的路线。关于尾矿中黄铁矿的特性及其加工后对电池性能的影响，仍有许多悬而未决的问题。该项目将研究来自多个地点（例如西班牙/葡萄牙）和不同年龄（新鲜尾矿和旧尾矿池）的含黄铁矿废物。目的是确定给定位置黄铁矿的可变性、将黄铁矿清洁到可接受的纯度所需的过程以及该纯度相对于电池性能的限制，以确定未来实施的合适位置。该研究将通过建模和模拟来考虑工业规模从尾矿中回收黄铁矿对环境的影响。
