In the briquetting process, fines are usually bound using water glass with hydrated lime. There are alternatives of equivalent quality, such as sulfite lye or molasses. For the cold briquetting of sponge iron, specific pressing forces in the range of 100 to 120 kN/cm are required, with similar forces being applied in the hot briquetting process (HBI).

Iron Ore Agglomeration Processes and their Historical …

The first machine that sintered Dwight-Lloyd-process iron ore was built in 1910 in the United States. The first Dwight-Lloyd sintering plant in Germany was built in1917. Though a large numbers of improvements have been made since then in the machine mechanical design and in the process of iron ore sintering, still the basic principle of the process remains the same.

Iron Ore Pelletizing Process: An Overview | IntechOpen

2017/7/10 · The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. This chapter shows the status of the pelletizing process ...

Direct reduced iron - Wikipedia

Process Direct reduction processes can be divided roughly into two categories: gas-based, and coal-based. In both cases, the objective of the process is to drive off the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 C (2,190 F)).
