Mineralogical, chemical, and physical characteristics of iron ore
201511 The “ore group” iron ore textural classification scheme (Table 2.7 and Figures 2.7 and 2.8) has been developed to link ore texture to downstream processing performance including lump/fines ratio, beneficiation, blast furnace lump physical and metallurgical properties, or fine ore sintering quality (Clout, 2002). The Ore Group
Comminution and classification technologies of iron ore
202211 Most of the high-grade hematite iron ores are typically subjected to simple dry processes of crushing and classification to meet the size specifications required for direct shipping ore (DSO). This involves multistages of crushing and screening to obtain lump (−31.5 + 6.3 mm) and fines (approximately −6.3 mm) products.
Iron ore pricing explained Fastmarkets
201867 Sinter fines and lumps make up the bulk of the seaborne iron ore market, and are the products most frequently traded on a spot basis, so daily pricing is used for the key 62% Fe, 58% Fe and 65% Fe fines, and lump premium references. By contrast, the beneficiated ore segment comprising pellet and concentrate is smaller in terms of both
Iron ore sintering ScienceDirect
202211 The sinter matrix bonds the initially loose iron ore particles into lumps of clinker-like material and is often called sinter bonding phase. The downdraft suction applied to the sinter bed helps to preheat the air sucked in from the top, to cool the sintered bed, and to heat and ignite the coke particles in the layer below the flame front.
Lump ore mining Britannica
Other articles where lump ore is discussed: iron processing: Lumps and fines: As-mined iron ore contains lumps of varying size, the biggest being more than 1 metre (40 inches) across and the smallest about 1 millimetre (0.04 inch). The blast furnace, however, requires lumps between 7 and 25 millimetres, so the ore must
Introduction: Overview of the global iron ore industry
202211 Turning to iron ore exports and imports, the tonnages are summarized in Table 1.1 for 2012 and 2018 (Australian Department of Industry, Science, Energy and Resources, 2021; US Geological Survey, 2020; United National Conference on Trade and Development (UNCTAD), 2021).As shown in Fig. 1.3, China is the largest iron ore

Blast furnace ironmaking and its ferrous burden quality
202211 The integrated iron and steelmaking route involves blast furnace (BF) ironmaking followed by basic oxygen furnace (BOF) steelmaking. The BF uses sinter, pellets, and lump ore as iron-bearing raw materials, and coke and pulverized coal as fuel and reducing agents to produce hot metal with consistent quality for the BOF process.

The important phrases in the present context, viz, 'mineral removed or consumed', 'processing' of 'run-of-mines (ROM)' and 'calibrated lump ore (CLO)' are not defined in the statutory scheme; and for the purpose of prescribing rate of royalty, iron ore is divided (in Entry No. 22 of the Second Schedule) into only three categories i.e. lumps
Alternative ironmaking processes and their ferrous burden
202211 Depending on the conditions used for final reduction of iron ore, alternative ironmaking technologies are typically divided into direct reduction (DR) and smelting reduction (SR) processes. The DR process involves the removal of oxygen from iron ore in its solid state at 750–1100°C using solid and gaseous reductants, such as natural gas
