Direct reduced iron, also called sponge iron, is produced from the direct reduction of iron ore 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 point of iron. Reduced iron derives its name from these processes,
directreduction of mangan iron ore. SHANGHAI ASM MINERALS CO., LTD. is a hi-tech, engineering group. We are specialized in the research, development, and production of industrial crushing, powder grinding, mineral processing equipments and other related devices.
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 are commercially available: gas-based and coal/oil-based.
The direct reduction process uses pelletized iron ore or natural "lump" ore. One exception is the fluidized bed process which requires sized iron ore particles. The direct reduction process can use natural gas contaminated with inert gases, avoiding the need to remove these gases for other use.
Manganese Ore is primarily used in steel and iron production among other uses like as an additive in unleaded gasoline and as pigments for the coloring of ceramics and glass. This page refers to the Manganese Ore with 32% manganese, and 20% iron in North China, Tianjin port from South Africa. This page provides Manganese Ore actual values
Mar 16, 2013· Direct reduced iron (DRI) is the product which is produced by the direct reduction of iron ore or other iron bearing materials in the solid state by using non-coking coal or natural gas. Processes which produce DRI by reduction of iron ore below the melting point of the iron are normally known as the direct reduction (DR) processes.
Oct 17, 2017· Reduction of iron ore to reduced iron form adds value and provides more compact products, which reduces shipping costs. The specific iron content of the direct reduced iron is a function of the iron content of the iron ore. Depending on the quality of the raw ore, direct-reduced contains about 90 to 94 percent iron, which is equivalent to pig
Alibaba offers 3 manganese mangan ore products. A wide variety of manganese mangan ore options are available to you, There are 3 manganese mangan ore suppliers, mainly located in Asia. The top supplying country or region is China, which supply 100% of manganese mangan ore respectively.
Direct reduced iron (DRI) process. In addition to the process route via the blast furnace process, there is another option for extracting crude steel from iron ores using the so-called direct reduced iron (DRI) process (secondary route).The starting point for the efforts to find an alternative to the blast furnace process was the relatively high process expenditure.
Nov 27, 2014· In the search for a pure, available iron source, steelmakers are focusing their attention on Directly Reduced Iron (DRI). This material is produced by the reaction of a low gangue iron ore with a hydrocarbonaceous substance. Commercially, DRI is generated in four different reactors: shaft (moving-bed), rotary kiln, fluidized bed, and retort (fixed-bed).
decades, a new route of ironmakin g has rapidly developed for direct reduction (DR) of iron ore to. metallic iron by using noncoking coal/n atural gas. This product is known as direct reduced iron

Direct reduction of iron ore refers to the conversion of solid iron ore to metallic iron without conversion to the liquid phase [37]. Majority of the direct reduced iron (DRI) [38] is produced by reacting iron oxide with hydrocarbon-based reducing gases produced from reforming natural gas
Oct 17, 2017· Reduction of iron ore to reduced iron form adds value and provides more compact products, which reduces shipping costs.

Nov 03, 2016· The direct reduction process. HBI is the product of reducing iron ore with natural gas. This is called the direct reduction process and is an environmentally-friendly production process; a DRI plant uses natural gas which is more environmentally sound than coke. The reduction process takes place in the reduction tower.
Direct reduction of iron is the removal of oxygen from iron ore or other iron bearing materials in the solid state, i.e. without melting, as in the blast furnace. The reducing agents are carbon monoxide and hydrogen, coming from reformed natural gas, syngas or coal. Iron ore
The ore then travels through a grinding circuit to reduce the particle size of the ore to between 150 and 250 μm, increasing the surface area to aid leaching. The ore is then added to a leach tank of sulfuric acid and ferrous iron (Fe 2+) in a 1.6:1 ratio. The iron reacts with the manganese dioxide to form iron hydroxide and elemental
CiteSeerX Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Brazilian hematite iron ore was reduced successfully in a rotary kiln with a gaseous reactant which was prepared by reforming butane within the kiln, using the beneficial effect of iron/iron oxide as an autocatalyst. The optimum ratio of the gaseous reactants, H2/CO2/C4H10, was used to prevent undesirable soot formation.
