Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe 2 O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H 2 O), 55% Fe) or siderite (FeCO ...

Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) to iron by a reducing gas or elemental carbon produced from natural gas or coal.Many ores are suitable for direct reduction. Direct reduction refers to solid-state processes which reduce iron oxides to metallic iron at temperatures below the melting ...

It requires higher temperatures (>1150° to 1250°C) to produce strong enough manganese ore pellets, which makes it a more expensive process. On heating of green pellets, manganese dioxide (MnO 2 ) and manganic oxide (Mn 2 O 3 ) dissociate in endothermic reactions that .
Iron ore pellets - an overview | ScienceDirect Topics In 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 .
Mines investigated methods to produce domestic iron ore pellets more competitively, using organic binders for agglomerating iron ore. The goals of this research were (1) to determine the physical and metallurgical pellet properties of pellets made with different types and dosages
22-05-2013· Iron ore pellets are one type of iron-rich, intermediate product used during primary iron and steel making. During pellet production, fine-grained iron containing minerals are liberated from low-grade ores, concentrated, and agglomerated into round balls that are thermally hardened to form "pellets".
Iron ore concentrate pellets are traditionally hardened at high temperatures in horizontal grates and grate-kiln furnaces. However, heat induration requires tremendous quantities of energy to produce high-quality pellets, and is consequently expensive. Cold bonding is a .
