elimination of the coalescence of and increase of the number of make it possible to increase the surface area of the sinter and obtain a substantial improvement in its reducibility. ferrites stabilize the micro pores and lead to a rise in porosity, thus achieving higher reducibility.
typical use in indian dri is in the range of 1.2 to 1.5 t- /t-dri. the use in advanced is between 1.05 – 1.2 t- /t-dri, which equals 20 – 25 gj/t-dri. this is significantly larger than the 15 - 19 gj/t-dri value obtained by using with 16% non-combustable fraction in south africa.

the sinter, pellets, metallurgical and quartzite are fed into the blast where the mixture, through a reaction with preheated air, is reduced into liquid hot and pig iron. thereafter, the hot metal, dri, scrap and lime are charged into the electric arc and an electric current is passed through the electrodes to form an arc.
in the energy sector, wood pellets are often used to replace coal with power plants such as drax replacing most of their coal use with woody pellet. as sustainability harvested wood does not lead to a long-term increase in atmospheric carbon dioxide levels wood fuels are considered to be a low-carbon form of energy.
