Our heavy-duty iron ore balling drums are relied on by some of the industry's top producers to process iron ore fines into pellets for the steelmaking process. The use of a disc pelletizer is a popular alternative approach to pelletizing iron ore fines, as this offers more control over pellet size and produces a more refined pellet product.
In the recent past, iron ore resources from Brazil consisted of relatively high-grade iron ore, commonly processed via multi-stage crushing/screening, gravimetric concentration, magnetic separation, and reverse flotation. However, the high-grade iron ore reserves are in decline, resulting in the need to process the lower grade itabirite iron ores.

Sintering is a thermal agglomeration process that is applied to a mixture of iron ore fines, recycled ironmaking products, fluxes, slag-forming agents, and solid fuel (coke). The purpose of the sintering process is manufacturing a product with the suitable characteristics (thermal, mechanical, physical and chemical) to be fed to the blast furnace.
The inadvertent generation of airborne particulate matter (PM) at iron ore processing plants can be a significant problem. During handling and transportation, the taconite pellets produced at the plants are subjected to abrasion which results in the generation of large quantities of fine material (Petavratzi et al., 2005).These fine particles can easily become …
Activities involved in finding, mining and processing iron ore at our Pilbara operations have been simplified in the following diagram. Rio Tinto operates 11 iron ore mines in the Pilbara and the specific sequence of activities varies from mine to mine. Excellence in planning, scheduling and quality control are fundamental to the process.
Iron processing - Ores, Smelting, Refining: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by …
The blast furnace uses coke, iron ore and limestone to produce pig iron. Coal traditionally has been a key part of the coke-making process. The coal is crushed and ground into a powder and then charged into an oven where it is heated to …
The mid-sized company JÖST + Co. KG from Duelmen in Germany is installing a high-tech system for processing iron ore pellets in Narvik, Norway. Kiruna, the northernmost city of Sweden, is home to an iron ore mine of the same name, which processes and stores pellets.
