Direct reduced iron Wikipedia

Process. Direct reduction processes can be divided roughly into two categories: gasbased, and coalbased. In both cases, the objective of the process is to remove the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 °C (2,190 °F)).

Integrated Production and Distribution Planning for the Iron Ore ...

The ore dressing production process is to convert the mined iron ore material into the iron ore concentrate. Also, in order to meet the demand of different ore concentrate products from backend customers in the supply chain, the frontend mining production and mineral processing/dressing production should be coordinated.

Improvement on the thermal cracking performance of ... ScienceDirect

As the ultrafine iron ore concentrate was used to prepare green pellets, the main problem was the serious cracking during the drying process. The fine particles contacted so closely that the porosity of green pellet was only %, which finally hindered vapor diffusion, and the cracking temperature was only 370 °C.

$Strengthening Granulating and Sintering Performance of Refractory Iron ...$

Strengthening Granulating and Sintering Performance of Refractory Iron ...

May Concentrate Iron ore, as a refractory iron concentrate, deteriorates the permeability of the sintered layer during the sintering process due to its fine particle size and poor granulating performance. Therefore, it cannot be widely used in iron ore sintering. In this study, the strengthening granulation of May Concentrate Iron ore using prepelletizing to expand its utilization ratio was ...

Circored Fine Ore Direct Reduction Plus DRI Smelting Springer

Comparison of Different Steelmaking Routes. When comparing Circored/EAF steelmaking with other stateoftheart routes, especially in terms of CO 2 emissions and cost, common battery limits need to be defined. We look here at the conversion of an iron ore concentrate to raw steel with all the required intermediate steps, forming the references for this comparison (see Fig. 3).
