Steelmaking

Steelmaking

With the ironore based route, hot metal is mostly produced from iron oxide ores in blast furnaces, and more rarely in smelting reduction plants, and is processed to make crude steel in oxygen converters. Sponge iron (direct reduced iron, DRI; hot briquetted iron, HBI) produced from iron ore in direct reduction plants is converted to crude steel in electric arc furnaces. With the scrapbased ...

Characterising the Blasting Properties of Iron Ore

Characterising the Blasting Properties of Iron Ore

Most iron ores occur in mine benches as complex mixtures of lithologies and ore types. This significantly complies their characterisation for both blast design and fragmentation modelling. A great deal of technical and research effort has been applied to the development of models to predict fragmentation from rock blasting. A number of quite useful engineering models are currently available ...
