According to statistical data on pollution, sintering plants rank second in terms of toxic emissions, after the incineration of municipal solid waste ( Menad et al., 2006; Remus et al., 2013 ).

Steelmaking and Refining Introduction to Chemistry

Steelmaking is the second step in producing steel from iron ore. In this stage, impurities such as sulfur, phosphorus, and excess carbon are removed from the raw iron, and alloying elements such as manganese, nickel, chromium, and vanadium are added to produce the exact steel required. Modern steelmaking processes are broken into two categories:

Iron processing Iron processing Ores: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite (Fe2O3), which is
