· In this process, a blend of pulverized coal and iron ore fines is pelletized. These pellets enter a doughnut-shaped rotary hearth furnace and undergo heating. At 1350 °C, reduction occurs within 8-10 minutes. The high heat enables pulverized coal to serve as the reductant, eliminating oxygen from the iron ore.

· How Iron Was Made. Iron making evolved over a few thousand years. Using the ancient "bloomery" method, iron ore was converted directly into wrought iron by heating the ore while at the same time melting the ore's impurities and squeezing them out with hand hammers. This is also called the "direct process." By the 1100s water
