Agglomeration. The available for smelting raw materials often do not have the required grain size upper than fine material simply cheaper. Therefore, various agglomeration processes are used to deliver such finer raw materials to the blast furnace. Küttner is involved in these processes at various points. Sintering The most common agglomeration process is the sintering of fine ore. ...

Highgrade hematite ore is referred to as direct shipping ore (DSO) because after it is mined, the ores go through a relatively simple crushing and screening process before being exported for use in steelmaking. Australia's hematite DSO from the Hamersley region in Western Australia averages from 56% to 62% iron. Like hematite ores, magnetite ores require initial crushing and screening, but ...

Sintering process is developed mainly to utilize under size of lump ore called iron ore fines; which otherwise, could not be charged directly in blast furnace. In order to conserve these, otherwise waste material, they are compacted together and made into lumps by a process known as is defined as the agglomeration of the Iron ore fines (generally <8 mm) by incipient fusion ...
