Phosphorous and iron recovery from steelmaking slag for effective recycling

该项目旨在了解控制钢铁厂炉渣中磷(P)分配的原理，并优化处理工艺，以产生富磷和富铁的循环利用流。澳大利亚矿石品位的变化，特别是磷含量的增加，使这些矿石产品中的很大一部分处于竞争劣势。该项目将采用一种综合的方法，从实验和理论上证明，如何操纵炉渣的关键特性来增强分配，并将这种分析与流体动力学相结合，以模拟分离过程的动力学。本研究的预期结果是：第一，为解决澳大利亚铁矿石中磷含量增加的问题提供可能的解决方案，这可能使未来的铁矿石产品在全球铁矿石市场中处于竞争劣势；第二，确定提高炼钢渣回收率的处理方法和做法，显著减少储存或填埋的材料量。

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.
