Iron processing - iron processing - Iron making 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 is made this way.
On Dioxin Formation in Iron Ore Sintering. IntroductionBackground. Ever since the discovery of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD Fs) in the offgas of one of the Dutch municipal solid waste incinerators (MSWI) in 1977 (1), there has been a growing concern on dioxins formed in this and in other thermal industrial processes.
Iron Ore Sintering The cheapest supply of iron ore to a steelmaker’s furnace is most often the sintered iron ore fines produced from their own or others sinter plants. Sintering takes the iron ore fines and agglomerates them into strong lumps capable of being used in the furnace. It also concent.

It got pelletisation facility for pellet making from the concentrate of beneficiation plant. Pellets are not for domestic consumption rather exported for.
Nov 25, 2018 Theory and Practice of Sintering of Iron ore. Sintering of iron ore is a generic term which is used to describe the process whereby a sinter mix (raw mix or green mix) of iron ore fines, fluxes, fuel (coke breeze) and plant return fines (e.g. mill scale, blast furnace dust, and returned sinter fines etc.) are converted into a particular form of agglomerate.
In this study, a number of commercial iron ore concen-trates were tested in a sinter pot to find their sintering char-acteristics in conventional sintering. The intensive mixer was used in an intensive mixing process5) and a separate granulation process to study the improvement of sintering with the iron ore blend containing the concentrate. 2.
Sintering is a process by which a mixture of iron ores, fl uxes and coke is agglomerated in a sinter plant to manufacture a sinter product of a suitable composition, quality and granulometry to be.
The experience in the plant is process in every industrial sinter plant thanks to the reflected in Table 1, which indicates the variation in accumulated experience of plant operators and the evolution productivity, BTP, maximum flame front temperature and progress in sintering know-how.
