Iron ore is a type of rock or mineral from which metallic iron can be extracted economically. It typically contains iron compounds in the form of oxides, carbonates, or sulfides, along with various impurities. The characteristics of iron ore can vary depending on the type of ore, but generally include:. Composition: Iron ore is primarily composed of iron, usually in the Enhancement of the quality of marketable iron ore products of ,The main indicators of the iron ore quality are the content of iron, silica, phosphorus and other components. It is ascertained that the quality of ore depends on its grainsize composition. The article proves that when crushing 160 mm fraction ore to 50 mm, Fe content is reclassified by sizes due to liberation of both martite and hematite at this grain

Longterm work practice shows that the energy consumption and wear part consumption of the crushing process are significantly lower than those of the grinding process, so more crushing and less grinding is an important principle that should be adhered to in the material crushing
112· The grinding setup refers to the socalled Malmberget method used at LKAB, characterized by a subsequent circuit of rod and ball mill grinding. The highest P 80 values were obtained by grinding only in the rod mill for 10 min (step A). Ball mill grinding for 25 min (step B) and 35 min (step C) gave a very narrow range of P 80 values.Fine Dry Grinding of Iron Ore for Pelletizing,620· The grinding requirement for unhydrated or hydrated and earthy hematites is governed by the fired product quality specifications. A minimum of 2200 cm²/gram Blaine specific surface area is generally necessary. Pellet quality, however, improves somewhat with finer grind on almost any material.
Enduron® high pressure grinding rolls (HPGR) can handle a wide variety of ores and particle sizes from fine pellet feed all the way up to coarse grinding of 75mm magnetite iron ore.. When it comes to feed material characteristics, the specific ore type is not detected by an Enduron® HPGR, however ore hardness, size and bed compressibility are important Research of iron ore grinding in a verticalrollermill,315· The grinding parts of a Loesche mill ( Fig. 1) are a rotating table (1) with a horizontal grinding track and rollers (2), which are pressed onto the table by lever arms and a hydro pneumatic spring system. Between the working surfaces of track and rollers, particle bed comminution takes place.
