Phosphate stabilisation of metalliferous mine wastes: The key to solving a major environmental issue?

矿山废物在人类产生的固体废物中所占比例最大。富硫化物矿山废弃物无约束排放对水、土、沙质量的影响。该项目将确立磷酸盐稳定的科学原理，其中包括向矿山废物和土壤中添加磷酸盐化合物，使其永久含有金属和酸。对这一新兴技术的深刻理解是对矿场进行任何可持续管理的先决条件。这项研究将为土地所有者、工业和管理人员提供未来管理工具的基础，以修复开采的土地和废物储存库。

Mine wastes represent the greatest proportion of solid waste produced by mankind. Unconstrained drainage from sulfide-rich mine wastes impacts on water, soil and sediment quality. This project will establish the scientific principles of phosphate stabilisation, which involves the addition of phosphate compounds to mine wastes and soils to permanently contain metals and acid. A solid understanding of this emerging technology is a prerequisite for any sustainable management of mine sites. The study will provide the foundation of future management tools needed by landholders, industry and regulators to remediate mined land and waste repositories.
