Iron processing - Iron making Britannica

This is any process in which iron is extracted from ore at a temperature below the melting points of the materials involved. Gangue remains in the spongelike product, known as direct-reduced iron, or DRI, and must be removed in a subsequent steelmaking process. Only high-grade ores and pellets made from superconcentrates (66 percent iron) are therefore really suitable for DR iron making.

Iron processing - Iron making Britannica

Iron processing - Iron processing - Iron making: The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron is made this way.

KOBELCO Pelletizing Process

include iron scrap, reduced iron pellets and reduced iron briquettes. Sintered ore is made by partially melting and sintering coarse iron ore 1 to 3mm in size into products having a size of 15 to 30mm. The sintering process uses the combustion heat of coke breeze (fuel). Pellets are made from iron ore …

KOBELCO Pelletizing Process

The sintering process uses the combustion heat of coke breeze (fuel). Pellets are made from iron ore that is finer than that used for sintered ore. The ore fine is formed into spheroids, called green balls, approximately 12mm in diameter. The green balls are fired into product pellets.
