The mineral industry is one of the main sectors of the Armenian economy and in 2017 accounted for % of its exports.. Armenia is a major producer of molybdenum, which is used in some highquality forms of steel, and other Zangezur coppermolybdenum complex possesses large molybdenum reserves that are concentrated in the Kajaran deposit.
Agglomeration is widely used in ferrous and nonferrous metallurgy to prepare smallsized ores and finely ground concentrates for smelting. One of the methods of agglomeration is briquetting, which can be done with or without binders. For briquetting with binders, roll presses are usually used. An alternative to roll presses can be extrusion presses, the main advantages of which are obtaining ...

It is an agglomeration process which converts iron ore fines into large, hard and porous lumps. This is done by incipient fusion of the iron ore fines when it is heated near to the melting point which binds them together to form lump. The diffusion bonds which is formed during recrystallization and formation of hematite and magnetite crystals also binds them without .

ABSTRACT In steel industry and in mines, a significant amount of ultrafines waste iron oxides and iron ore fines is generated. Utilizations of these fines are required to reduce the environmental hazards and conserve the natural resources. Some of these fines are normally used in sintering practice. However, sintering has a limitation of accepting ultrafines materials.
In this case the iron ore fines and other iron bearing recycling materials are mixed with fluxing material, moisture and solid fuel normally coke breeze and fed to the permeable grate of sintering machine. The upper surface is ignited and the air is drawn through the bed with combustion front passes downwards accompanied by a series of physical and chemical changes which produce the sinter.

number of organic polymeric binders for agglomeration of iron ore have been developed in the last decades (see references [314] in [6]). The main advantage of organic binders compared to traditional inorganic binders, like bentonite, is that the former are completely eliminated 1 . during the heat treatment of iron ore pellets and thus do not introduce any contaminants to the final .
