Iron Ore Geometallurgy - Examining the Influence of Ore ...

The properties of iron ore sinter - commonly defined by measures of tumble strength, reduction degradation and reducibility - have a major impact on blast furnace performance. These properties are largely influenced by raw material properties, in particular the bulk ore composition. Despite this importance, there is a lack of quantitative data on the impact of ore chemical composition on iron ...
