Differential solidification of steel slag to create a fertiliser co-product

该项目旨在开发一种在炉渣仍处于熔融状态时从炼钢炉渣中分离磷的工艺。澳大利亚铁矿石品位的变化，特别是磷含量的增加，使澳大利亚铁矿石产品处于竞争劣势，并招致重大的经济处罚。该分离方法旨在促进钢铁厂内富铁流的再循环和用于农业的富磷副产品的生产。预期收益包括增加钢渣的利用率，创造有价值的化肥副产品，减少温室气体排放，以及减少对澳大利亚铁矿石的处罚。

The project aims to develop a process to separate phosphorus from steelmaking slag while the slag is still molten. Changing iron ore grades in Australia, especially increasing phosphorus content, places Australian iron ore products at a competitive disadvantage and attracts a significant financial penalty. The separation process is intended to facilitate recycling of an iron rich stream within the steelworks and production of a phosphorus rich co-product for agriculture. Benefits are anticipated to include increased utilisation of steel slag, creation of a valuable fertiliser co-product, decreased greenhouse gas emissions, and a reduction in the penalty applied to Australian iron ores.
