called hot metal. In direct reduction, iron remains in solid state and the product is the so-called direct reduced iron DRI. Generically, the iron ore products for ironmaking can be classified as shown in Table 1 . Pellets are balls formed by rolling moist concentrates and fines iron ores of different mineral-
semiautogenous grinding SAG and metallurgical pilot plants on iron ores, including extremely large plants treating up to 1,000 tonnes of ore and lasting for 6 months. Many complex circuits using autogenous grinding, de-sliming, magnetic separation, gravity separation, selective flocculation, and flotation have been run in our laboratories.
HPGR in iron ore industry ThyssenKrupp HPGR mills have shown themselves good in iron ore industry. The first HPGR was employed in iron ore mining industry in the 1990s in grinding iron con-centrates for pelletizing. That time the grinding rolls had smooth or ribbed wrought shells lining. That technology

The results indicated that the iron phase in reductive iron ores was predominantly metallic iron below 20 m. By applying ultrafine grinding-magnetic flocculation separation MFS to the raw ore 29.85 Fe, a concentrate assaying 74.12 Fe with 81.45 iron recovery was obtained.
Preparing Iron Ore for Pelletizing Balling Iron ore must go through a lengthy pre-processing stage before it can be pelletized a series of steps that work to beneficiate and concentrate low-grade ores. This process varies depending on the ore source, but typically involves various stages of crushing and grinding to reduce the size of the ...
Nov 01, 2016 1. Introduction. The processing and utilization of iron ores are intimately linked to their mineralogical characteristics, liberation pattern, and the nature of inclusion of the impurities such as SiO 2, Al 2 O 3, P and S.The goethitic, oolitic and wad type ores containing high silica and alumina are very difficult to process by conventional beneficiation techniques.

A process for upgrading low-grade magnetite-containing iron ore with minimum fine grinding. The dry ore is first comminuted to between about three-fourths inch and 10 mesh particle size and magnetically separated. The dry tailing is discarded and the concentrate is ground to between about 20 and 100 mesh and again subjected to dry magnetic separation.
A significant quantity of chromite ore is available in form of fines and is friable in nature. Agglomeration is necessary for utilizing these fines. Briquetting gives green agglomerates with inferior high temperature properties. Pelletization requires further grinding of the naturally available ore fines and the subsequent fir-
