The haematite ore in South Africa is processed in a dry process to a HQ lump ore with 64 % iron content and a sintered fine ore with 63.5 % iron content. For fine ore beneficiation, wet processes are used. Capacity at the Minas Rio is to be increased from 26.5 Mta capacity to 28 Mta in the forthcoming years. Ore is beneficiated in a wet process.
Imports In 2021, Ethiopia imported $42k in Iron Ore, becoming the 0th largest importer of Iron Ore in the world. At the same year, Iron Ore was the 0th most imported product in Ethiopia. Ethiopia imports Iron Ore primarily from: N/A.
Karara comprises a large-scale, long-life magnetite orebody amenable to bulk mining and processing. Magnetite ore has lower iron content (34-36% Fe) than hematite ore (58-64% Fe). It must be upgraded by a complex ore treatment process (beneficiation) to produce a high-grade (+65% Fe) concentrate for steelmaking.
