Compressive Strength Of Iron Ores

Compressive Strength Of Iron Ores

A method of producing an iron ore briquette that is suitable for use as a blastfurnace or other direct reduction furnace feedstock which includes the steps of (1) mixing ore and a flux to form an ore flux mixture (2) pressing the ore flux mixture into a green briquette using a low roll pressure and (3) indurating the green briquette to form a fired briquette.Composite briquettes or pellets consisting of iron ore carbon and a binder are a source of direct reduced iron (DRI) In the handling of green and reduced briquettes high strength is important.
