WebOct 2, 2024 · Iron ore concentrate is an output product from processed iron ores that have been milled (crush, grind, magnetic separation, flotation) to separate deleterious elements and produce a high-quality product. Sintering and pelletizing are economic and widely used agglomeration processes to prepare iron ore fines/iron concentrate for ironmaking use. WebIn a DR process, iron ore pellets and/or lump iron ores are reduced by a reducing gas to produce DRI or hot briquetted iron (HBI). Depending on the generation of the reducing gas, two different DR processes are commercially available: gas-based and coal/oil-based.
