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

矿山废物占人类产生的固体废物的最大比例。富含硫化物的矿山废物无限制排放对水、土壤和沉积物质量的影响。该项目将建立磷酸盐稳定的科学原理，包括在矿山废物和土壤中添加磷酸盐化合物，以永久包含金属和酸。对这一新兴技术的扎实了解是任何矿场可持续管理的先决条件。这项研究将为土地所有者、行业和监管机构修复开采区和废物库所需的未来管理工具奠定基础。

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.
