In Minas Gerais, the average content is 40% iron, contained in rocks known as itabirites.

Direct reduced iron Wikipedia

Direct reduction processes can be divided roughly into two categories: gas-based, and coal-based. In both cases, the objective of the process is to remove the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 °C (2,190 °F)). The direct reduction process is comparatively energy efficient. Steelmade using DRI requires significant

Dry processing of magnetic iron ores addressing cost and

The iron ore industry has reached the end of an unprecedented period of expansion triggered by China's demand for iron ore. Lower ore prices have led producers to focus on optimising mining operations while extracting the maximum tonnage from the infrastructure presently in place or from projects already underway. A rising global surplus is expected to further force ore prices down and lead to
