1. The Bessemer Process. The Bessemer steel making process consists of blowing air through molten pig iron contained in a special furnace known as a converter which shaped like a huge concrete mixer (Fig. 4.2).The converter is made of steel plates lined inside with a refractory material. The type of refractory lining used depends upon the character of …
In this process, iron ore, coke (a form of carbon), and limestone are fed into the furnace, where intense heat and chemical reactions extract molten iron. Innovations in blast furnace technology, including hot blast systems, oxygen enrichment, and refractory materials, have significantly improved productivity and environmental performance.
ABSTRACT. The behavior of iron ore pellet binders is complex. Any pellet binder is subject to a handful of practical requirements: that it be readily dispersed through a pellet, that it effectively controls the movement of water within the pellet, and that it contributes to the inter-particle bonding within the pellet.
Iron processing - Smelting, Refining, Alloying: The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron …
Smelting Reduction. Figure 2: The smelt reduction vessel (SRV) is the core technology component of the Hismelt process. Source: RioTinto While years of ironmaking technology innovations have optimized blast furnace productivity, two alternative processes—smelting reduction and direct iron reduction— are growing in adoption. The …
Sponge iron is a highly ferrous ore from the direct reduced iron process! In order to prevent excessive re-oxidation of the sponge iron in the ambient air, it must be cooled down in the lower region of the shaft furnace. Carburisation as in the blast furnace process does not occur in the DRI-process, as coke is not used as a reducing agent.

Schematic flow chart of the reduction-smelting process of iron ore using non-coking or charcoal as reductants. Therefore, the availability of DRI using non-coking coal as a reducing agent is determined by the availability of iron ore with over 65% Fe quality and the availability of a cheap source of non-coking coal.
The final stage in iron ore processing is ironmaking, where the iron ore is transformed into molten iron through a process called reduction. The most common method of ironmaking is the blast furnace route. In a blast furnace, iron ore, coke (carbon), and fluxes (limestone or dolomite) are loaded into the furnace from the top.
Mekanism provides 4 tiers of systems to process ores and obtain two to five ingots from 1 ore. The complexity of the systems rises with each tier and at the higher tiers various secondary machines are required to produce consumables for the main ore processing line. The following page shows the layout of these systems as well as some in-game …
Iron processing - Ores, Smelting, Refining: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed iron-bearing minerals are oxides, and …
Schematic flow chart of the reduction-smelting process of iron ore using gaseous reductants. 9 Iron Ores and Iron Oxide ore particle reaction rate, and reduction temperature as major parameters which affect the overall quality of the molten iron and hydrogen solubility in slag formation produced under severe thermal reduction of the …
Fig 3 Types of processing ores. The wet processing (Fig 4) is normally practiced for low / medium grade (60 % Fe to 63 % Fe) hematite iron ore. The wet process consists of multi-stage crushing followed by different stages of washing in the form of scrubbing and / or screening, and classification etc., but the advantage is only partial …
