R. FINDORÁK et al.: POTENTIAL OF ILMENITE SAND APPLICATION IN THE IRON ORE MATERIALS AGGLOMERATION Balling tests of the ilmenite sand were carried out with the objective to evaluate the possibilities of its application in the processes of the fi ne grain materials agglomeration, as is the case of the sintering and pelletizing processes.
Circored® is a two stage fluidized bed process, reducing iron ore fines directly without prior agglomeration, that operates at low reduction temperatures using pure hydrogen as the reducing gas. The hydrogen is produced by means of natural gas reforming, but hydrogen from sources other than a steam reformer, from water electrolysis, can also be used.
In 1976 CVRD started the investigation of organic binders application for iron ore agglomeration. The ore was mixed in a Eirich Mixer with quantities of Peridur ranging from to % and pellets were prepared in a laboratory disk. At first the results were not satisfactory at all.
Australia is one of the world's leading producers of iron ore which is used partly in the domestic iron and steel industry [...] but is largely exported to countries such as Japan, South Korea, Taiwan and China.
Raw or refined petroleum was used for clustering. Anhydrous calcium chloride was used as the source of calcium ion for activation and sodium silicate as a depressant of iron oxides. The agglomeration process was performed in a ball mill, in which conditioners were added, collector and binder.
Apr 10, 2018· At its basic level, iron ore beneficiation consists of the following steps: 1. Crush and grind to a sufficiently fine size that the iron oxide minerals are broken free of the gangue minerals like silica (Liberation) 2. Physically sort the mineral ...
agglomeration during the process of iron ore pelletizing. The majority of iron ores must be ground to a fine particle size to allow the iron oxides they contain to be concentrated, and the concentrate must then be agglomerated back into large enough particles that they can be processed in blast furnaces.
Aug 01, 2019· The new process is said to be the world's first directreduction (DR) process for ironore concentrates from ore beneficiation not requiring any preprocessing, like sintering or pelletizing. The new technology can be applied to all types of beneficiated ore and .

As we know, the innovative process named composite agglomeration process (CAP) has a series of advantages compared to traditional sintering process (TSP). In CAP, part or all of the ironbearing dusts is made into green pellets with 5–15mm in diameter, while the rest of ironbearing dusts and all of the other fine ores is granulated after mixing with fuels, fluxes and return fines.
World resources are estimated to be greater than 800 billion tons of crude ore containing more than 230 billion tons of iron. The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering process. Sinter is the primary feed material for making iron and steel in a blast furnace.

Iron Ore Agglomeration Ø Sinter Process The sinter process was introduced around 1910 to treat flue dust extracted from blast furnace exhaust gases. It was quickly adapted to agglomerate fine ore and its use spread rapidly. At the sinter plant, preblended fine ore is mixed with: • coke breeze (small particles of coke from the screening plant);
iron ore fines cold briquetting process reduction of iron ore to metallic iron in the solid state at process temperatures less agglomeration processes like pelletisation, briquetting and nodulisation are include fine iron ores, additives (, lime or olivine), and ironbearing ..
