iron. The magnetic concentrate designated direct reduced iron (DRI) was obtained by a twostage magnetic separation process, namely, the rough concentrate obtained from the first separation step was magnetically separated again. The main evaluation indexes of the test results were the iron grade and the iron recovery of DRI. The iron recovery ...

Coal gasifiion for DRI production – An Indian solution

Direct Reduced Iron (DRI) production has increased tremendously since 1980, from essentially zero to over 21Mt in 2008, as shown in Fig 1. Of the total DRI production in 2008, 74% was produced from coal in rotary kilns and 26% from natural gas in shaft furnaces. India is now the world's largest producer of DRI. Currently, there are two ...

Direct Reduced Iron (DRI) Refractories

Direct Reduced Iron (DRI) Refractory. Direct Reduced Iron (DRI) is an alternative to the blast furnace processes to produce a source of iron units. Greater availability of natural gas has replaced classic coke oven coalbased processes. Several processes are commercially viable today and they use a number of ways to achieve good quality DRI.

LowCarbon Production of Iron ...

· Direct Reduced Iron (DRI): This iron production process directly reduces iron ore in solidstate with the reaction temperature below the melting point of iron. Reducing gases are produced from natural gas (gasbased DRI) or coal (coalbased DRI) called syngas, a mixture of H2 and CO.

Direct reduced iron process

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 socalled 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.

DirectReduced Iron

Direct reduction (DR): Direct reduction involves the production of solid iron from iron ores and a reducing agent (, natural gas). The solid product is called DRI and is mainly applied as feedstock in EAF. The direct reduction process has been commercialized since the 1970s and a variety of processes have been developed. (2)

Midrex Process for Direct Reduction of Iron Ore. Midrex is an ironmaking process, developed for the production of direct reduced iron (DRI). It is a gasbased shaft furnace process is a solid state reduction process which reduces iron ore pellets or lump ore into DRI without their melting using reducing gas generally formed from natural gas.
