The iron grades of the other iron ores are lower than 64%, and the return fines from BF sieving exhibits the lowest iron content. Ore-D and Ore-E are typical limonite ores with high CW.
For example, the daily, weekly and monthly indices are listed because of the varied liquidity displayed by different parts of the market. Sinter fines and lumps make up the bulk of the seaborne iron ore market, and are the products most frequently traded on a spot basis, so daily pricing is used for the key 62% Fe, 58% Fe and 65% Fe fines, and lump premium references.
Moreover, the SiO 2 content in imported iron ores is relatively lower than that of the domestic iron ore concentrates, which helps to produce sinter with lower impurity levels. However, an excessively low SiO 2 content would lead to insufficient generation of SFCA (Quaternary compound of calcium ferrite containing silicate and alumina) under .
