This chapter introduces the principle of how low-grade iron ores are upgraded to high quality iron ore concentrates by magnetic separation. Magnetite is the most magnetic of all the naturally occurring minerals on earth and can be readily extracted by low-intensity magnetic separators from magnetite ores. On the other hand, oxidized iron ores ...

High-pressure grinding rolls reached great popularity for pressing iron ore concentrates since its first application in the 1990s. For this particular application, mathematical models describing HPGR performance on the basis of operating conditions and feed characteristics have successfully been used by the authors to map industrial-scale operations …

If you are a member, please login using the orange button at the top of the page to view the full article, or register. If you are unsure of your ...

Fig. 2 illustrates the iron ore beneficiation process, particularly magnetic separation, resulting in the generation of inevitable tailings. Due to the characteristics of iron ores and the conditions during beneficiation, it is inevitable that approximately 2.5–3 tons of IOTs are generated for every 1 ton of iron ore concentrate produced [7].In 2019, the global annual …

Five iron ore agglomeration technologies can be defined: briquetting, nodulization, extrusion, pelletization and sintering.

Sintering. Iron ore sintering consists of heating a layer of fines until partial melting occurs and individual ore particles fuse together. For this purpose, a traveling-grate machine is used, and the burning of fine coke (known as coke breeze) …

Depending on the ore characteristics, including extraction ore and tailings, iron concentrates with varying levels of magnetic sulfur impurities can be produced. The presence of such impurities can result in penalties in iron concentrate sale contracts, with a tolerated sulfur content limit typically set at 0.1% S (Compañía Minera del ...
