Numerous iron ore deposits are hosted within the Meso to Neo-Archean banded iron formations (BIFs) extending across the Singhbhum-Orissa Craton, eastern India. Despite the widespread distribution of BIFs, which forms part of the iron ore group (IOG), heterogeneity in their grade and mineral composition is occasionally observed even within a single ore deposit.

DR-Grade Pellets. Direct Reduced Iron (DRI) is a high quality metallic product (~90 percent pure iron) produced by the direct reduction of iron oxide at a temperature below the fusion point of iron. It is primarily used in electric arc furnaces (EAF), but can also be used by blast furnaces and other iron and steelmaking applications.

Vale will invest 11 billion reals in dry mineral ...

2019-5-14  Dry mineral processing is related to the grade of iron in the mined ore. In Caracas, because of the high iron grade (more than 64%), the ore only needs to be crushed and screened, so it can be screened according to the size (particle size) of the ore. In Minas Gerais, iron exists in rocks known as "iron quartzite" with an average iron grade of 40%.
