A. Jankovic, in Iron Ore, 2015 Abstract. Hematite and magnetite, the two predominant iron ores, require different processing routes. High-grade hematite direct shipping ores (DSOs) generally only require crushing and screening to meet the size requirements of lump (typically between 6 and 30 mm) and fines (typically less than 6 mm) products.Low-grade hematite ores require additional

Optimization of Biomass Materials for use in the Sponge

1.5.2 The Sponge Iron Process The sponge iron process is a process for producing sponge iron, which is porous iron [1]. The raw material used for producing sponge iron is magnetite ore concentrate (Fe 3 O 4), which is the material that will become reduced [1]. The reduction mixture consists of coke and anthracite [1]. Figure 1.1 shows the

Direct-Reduced Iron an overview ScienceDirect Topics

2012-1-5  Iron ore concentrate (magnetite or hematite or their mixtures) and noncoking coal mixed in pellets are processed for 10 min by a single-stage heat treatment in an RHF, yielding high-quality (96–97% Fe), slag-free iron nuggets. These nuggets are easier to handle than DRI or hot-briquetted iron and are processed in EAF or (after remelting) in BOF.
