The most common agglomeration process is the sintering of fine ore. As a rule, larger amounts of circulation material are used in the sintering plant. This often leads to increased emissions. A good solution here is a cloth filter system with a semi-dry sorption process. K ttner works here with L hr in a very close cooperation.

The agglomeration process in which lumps are made by compacting the iron bearing fines and dust with addition of binder and also de-airing these mixtures inside the vacuum chamber of the briquetting machine. So, briquetting process is developed to meet these demands. This process aims at recycle and reuse of the low grade iron ore and plant fines.
A process is described for the agglomeration of fine particles utilizing a combustible agglomerating agent dispersed in an aqueous emulsion. The process is particularly directed to the handling of fine metal containing particles, originating as by-products or waste products of metallurgical processes, which are to be stored or recycled to metal extractive process steps.
Composite agglomeration process CAP of iron ore fines has been proved an effective route for ironmaking burden production, and is characterized by low the fuel consumption and high the productivity compared with the traditional sintering process. Sintering behavior of pelletizing feed in CAP has not been studied fully yet.

Mar 09, 2013 The process of sintering begins with the preparation of the raw materials consisting of iron ore fines, fluxes, in-plant metallurgical waste materials, fuel and return fines of the sinter plant. These materials are mixed in a rotating pelletizing drum and water is added in order to reach proper agglomeration of the raw materials mix.
Feb 01, 2012 Sintering and pelletizing are two common agglomeration processes. In a BF, pig iron and blast furnace gas BFG is produced by reducing iron ore sinters and pellets with coal and coke. BFG is partly used for other processes within the iron and steelmaking plant, and the rest can be exported for power generation.
Mar 18, 2020 Effect of distribution of iron concentrates between pelletized and matrix feed on the preparation of blast furnace burdens from two different kinds of fine iron concentrates magnetite and hematite by composite agglomeration process CAP was explored. It was found that when the mass ratio of iron concentrate A magnetite to iron concentrate B hematite in the mixed feed was

The utilisation of low-grade raw materials such as fine iron ore and semi-soft coking coal, and reduction of CO2 emissions are important issues in the ironmaking process. To solve these issues, a new process called PosPRA POSCO prereduced agglomeration process has been developing at POSCO. It focuses on the reduction of carbon composite iron ore briquette in travelling grate.
Sep 01, 1974 Beneficiation of a phosphoriferous iron ore by agglomeration methods. Int. J. Miner. Process., 1 231--241. The Snake River iron ore deposit, in the northern Yukon, Canada, is an enormous, potentially valuable natural resource. Conservative estimates indicate that the deposit contains some thirty thousand million tons of ore.

Mar 02, 2013 Iron making. Recrystallization is a process by which deformed grains are replaced by a new set of undeformed grains that nucleate and grow until the original grains have been entirely consumed. Recrystallization is usually accompanied by a reduction in the strength and hardness of a material and a simultaneous increase in the ductility .
