Iron ore supply and demand outline 1.1 Types of iron ore. Iron ores can be classified in different ways. The most important has to do with the iron content. In many cases, ore with a total iron content of 60% to 63%, or greater, is regarded as high grade, and ore with a lower iron content is regarded as low grade.
Figure 1 shows the amount of CO2 emissions in each of the unit operations relating to mining operations and mineral processing. The majority of steel production is supported by iron ore sourced from high grade hematite deposits, although a significant fraction comes from magnetite deposits.

The particle separation in a wet high intensity magnetic separator depends on a number of variables. Applied magnetic field, particle size, and wash water rate play a vital role among them. Influences of these important variables were studied in detail following 33 full factorial designs of experiments using a laboratory/pilot scale wet high intensity magnetic separator (Gaustec G 340 Minimag).
Apr 03, 2014Iron ore is a mineral which is used after extraction and processing for the production of iron and steel. The main ores of iron usually contain Fe2O3 (70 % iron, hematite) or Fe3O4 (72 % iron. magnetite). Ores are normally associated with unwanted gangue material. Grade of iron ore is usually

Edison saw dollar signs in magnets. Unfortunately, that didnt pan out financially. Probably the biggest financial failure of Edison's career was the magnetic ore separator. The idea, which Edison's laboratory experimented with during the 1880s and 1890s, was to use magnets to separate iron ore from unusable lower grade ores.
