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 is used mostly in pellet and/or lumpy form.
They are then used to help heat the air blast, required if blast furnace is to reach the high temperatures needed to produce molten iron. The stock level is constantly 'topped up'. Molten iron ore is 'tapped' at the bottom of the blast furnace, poured into the iron ladle and removed for use. The slag is removed at the tap hole.
Twenty different iron ore pellets, consisting primarily of Hematite (Fe2O3) phase, were subjected to 'simulated' reduction studies. A wide range of reduction time periods, Rt of 122 to 211 minutes, were obtained. Detailed microstructural characterizations were then conducted at different locations of ten selected specimens. The Rt did not …

High-grade ore production increased by 22% (+1.3 mln t), while production of cuprous ores decreased by 4% (–0.2 mln t).
Guide for manufacturing and making Pig Iron. Following three distinct operations are involved in the manufacturing process of pig-iron: (1) Dressing (2) Calcination and roasting (3) Smelting. (1) Dressing: The iron ores as obtained from mines are crushed into pieces of size of 25 mm diameter. This is achieved in the rock crushers of ordinary type. The …
In 2013, CITIC Pacific Mining had put into operation a first line from a total of six for the production of a magnetite iron ore concentrate in the Pilbara region. The capacity of the Sino-Iron project (Fig. 12) is 180 000 tonnes per day or 24 Mta. In contrast to the Iron Bridge project, wet beneficiation with SAG mills, wet ball mills and wet ...
Originally, the iron was collected in pools called pigs, which is the origin of the name pig iron. Figure (PageIndex{1}): A Blast Furnace for Converting Iron Oxides to Iron Metal. (a) The furnace is charged …
Figure 15.1 shows the flow sheets for modern straight grate and grate-kiln pelletizing processes. The straight grate process consists of a single furnace, which is divided into different zones for drying, preheating, and indurating green balls and zones for cooling the fired pellets. ... A compilation of iron ore pellet production, volumes 2010 ...
Best-in-Class Steel Producer. Cleveland-Cliffs is the largest flat-rolled steel producer in North America. Our competitive advantage as an integrated steel company is based on our ability to operate the entire production flow from the extraction of iron ore, to steelmaking, rolling, coating, finishing, stamping and tooling steel products.
Iron ore handling, which may account for 20–50% of the total delivered cost of raw materials, covers the processes of transportation, storage, feeding, and washing of the ore en route to or during its various stages of treatment in the mill.. Since the physical state of iron ores in situ may range from friable, or even sandy materials, to monolithic …
The blast furnace is a counter-current gas/solids reactor in which the descending column of burden materials [coke, iron ore and fluxes/additives] reacts with the ascending hot gases. The process is continuous with raw materials being regularly charged to the top of the furnace and molten iron and slag being tapped from the bottom of the ...
