Use of Iron Ore Pellets in Blast Furnace Burden – IspatGuru

Jun 13, 2014  In the mid 1980s, a number of pelletizing and blast furnace trials were conducted to evaluate the benefits of limestone dolomite fluxed pellets. Towards the end of the decade, fluxed pellets had been firmly established as a major product, accounting for about 30 % of North America’s pellet

Iron Oxide Pellet - an overview ScienceDirect Topics

The blast furnace process is primarily used in the carbothermic reduction of oxides, such as iron, zinc, and lead. Most of the iron ore bodies commercially explored consist of iron oxides. Consequently, rich iron ore and/or iron oxide pellets formed from concentrate can be added directly to a blast furnace (see Iron Production).
