Driving investments in ore beneficiation and scrap upgrading
Cost analysis of iron losses due to an ore beneficiation and a scrap upgrade. The value of iron lost in an extra beneficiation operation is shown in Fig. 11 for three hypothetical cases A-C for tailing grades of (A) 10% Fe, (B) 15% Fe and (C) 20% Fe, which all contain 70% SiO 2. Data from the calculations are given in Table 12. The iron …Web

The majority of world crude steel is made from the BF-BOF route. Ores carrying very high quantities of hematite (greater than ∼60% iron) are known as "natural ore" or DSO, meaning they can be fed directly into the BF-BOF route. However, low-grade ores need to be beneficiated before they can be used to make steel.Web
