Introduction: Overview of the global iron ore industry
This chapter first provides an overview of world iron ore production and trade, as well as reserves and resources, followed by a summary of the key mining known as sinter. Iron ore sinters are suitable porous materi-als obtained by agglomeration processes of iron ore fine particles. These agglomerates are widely employed in blast Low Carbon Sinter Making: Use of Inert Gas to Improve

The halogens contents in sample matrix were expressed as a percentage mass fraction (%), and calculated by the following equation (1): (1) X = (C s − C o) V × f 1000 × 1000 × m × 100 % whereas,. X is the mass fraction of fluorine or chlorine in the sample;. C s is the concentration of halogens 0.2 India possesses about one-fourth of the total world reserves of iron ores and is the biggest single country possessing such large quantities of iron ore deposits. She is a major world supplier of the ore and large quan- tities are regularly exported from the various Indian ports. The exportsIS 1493 (1959): Methods of Chemical Analysis of Iron Ores
