Differential solidification of steel slag to create a fertiliser co-product. 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 product ....Differential solidification of steel slag to create a fertiliser co-product. 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.Read moreRead less
Low emission iron and steelmaking using hydrogen to pre-reduce lump ore. This project aims to develop and apply a new route of lump iron ore pre-reduction with hydrogen or H2-enriched gases for ironmaking to minimise CO2 emission from steel production. The route will be built up on the base of H2 reduction kinetics of iron ore and with novel technologies such as CO2 recycle and H2-heating using hot blast, underpinning the hydrogen economy by addressing the environmental concerns in mineral and s ....Low emission iron and steelmaking using hydrogen to pre-reduce lump ore. This project aims to develop and apply a new route of lump iron ore pre-reduction with hydrogen or H2-enriched gases for ironmaking to minimise CO2 emission from steel production. The route will be built up on the base of H2 reduction kinetics of iron ore and with novel technologies such as CO2 recycle and H2-heating using hot blast, underpinning the hydrogen economy by addressing the environmental concerns in mineral and steel industries. It is not only significant for low-carbon steel production, but also for better fundamental understanding to develop the future zero-emission iron and steelmaking with hydrogen. The project will be very beneficent because it increases the use of lump iron ore and expends Australian export of iron ores.Read moreRead less
