This project aims to understand the principles that control phosphorus (P) partitioning in steel plant slags and to optimise the treatment process to produce P- and Fe-rich streams for recycling. Changing ore grades in Australia, especially increasing P content, are placing a substantial proportion of these ore products at a competitive disadvantage. The project will use an integrated approach to demonstrate, experimentally and theoretically, how key properties of slags can be manipulated to enhance partitioning and couple this analysis with fluid dynamics to model the kinetics of the separation process. The expected outcomes of this research are to: first, provide possible solutions to address the increasing P content in Australian iron ores, which could place future ore products at a competitive disadvantage within the global iron ore market; and second, to identify treatment methods and practices which would promote higher recycling rates of steelmaking slag, significantly reducing the volume of material stockpiled or sent to landfill.

该项目旨在了解控制钢铁厂炉渣中磷（P）分配的原理，并优化处理过程，以产生用于回收的富P和富Fe流。澳大利亚矿石品位的变化，特别是磷含量的增加，使这些矿石产品的很大一部分处于竞争劣势。该项目将采用综合方法，从实验和理论上演示如何操纵炉渣的关键特性以增强分配，并将此分析与流体动力学结合起来，以模拟分离过程的动力学。这项研究的预期成果是：第一，提供可能的解决方案，以解决澳大利亚铁矿石中磷含量不断增加的问题，这可能会使未来的矿石产品在全球铁矿石市场上处于竞争劣势;第二，确定处理方法和做法，这将促进炼钢炉渣的更高回收率，大大减少材料的储存或送往填埋场。
