Product: Iron Ore; Origin: Colombia, Mexico, Australia, India, Philipines, Peru, Chile Brazil; Australia exports three distinct types of iron ore from its Pilbara mines. These are known as blended lump ore, blended fine ore, and Yandi (HIY) fines. Crushing and screening processes divide the ore into lump and fines. The lump

General process information. High-grade iron ore is crushed for sizing, producing both fine ore as well as lump ore. To beneficiate low-grade ore, lump ore is first grinded into finer particles called grinded ore. Both fine and grinded ores are then subjected to pre-treatments before they can be charged into the blast furnace;

Vale is the world's leading producer of iron ore and pellets. By means of various industrial processes incorporating cutting-edge technology, iron ore is processed and then sold to steel companies. The iron ore On top of this, the ore needs to be strong enough not to be crushed thereby obstructing the blast furnace. Thus

Lumps and fines. Crushing. As-mined iron ore contains lumps of varying size, the biggest being more than 1 metre (40 inches) across and the smallest about 1 millimetre (0.04 inch). The blast furnace, however, requires lumps between 7 and 25 millimetres, so the ore must be crushed to reduce the maximum particle size.

For better blast furnace produc- tivity, the ratio of maximum to minimum size of lump ore charged in the furnace is approximately 3:1 with the top size of about 30 mm. Almost all the iron ore processing plants producing calibrated ore both for domestic as well as export oriented market employ two stages of crushing except in

The process of Pelletization helps converting Iron Ore Fines into “Uniform Size Iron Ore Pellets” that can be fed in the blast furnaces or in the DRI kiln (DRI). Why Pelletization? Pelletization is the making with lower fines generation. Maintenance cost is low as there is not need for crushing and screening of iron ore lumps.
