Iron (Fe) is a metallic element that constitutes 5.6% by weight of the Earth's crust and is the fourth most abundant element in the crust. Iron ores are rocks from which metallic iron can be economically extracted. The principal iron ores contain hematite (Fe 2 O 3) and magnetite (Fe 3 O 4 ). Hematite is an iron oxide mineral.

"Beneficiation" of iron ore includes concentration, generally by physical removal of unwanted gangue; also, considered beneficiation is the regulation of product size, or other steps such as agglomeration to improve its chemical or physical characteristics prior to processing. ... Wet grinding–dry grinding. 2. Open-circuit grinding ...

The magnetite beneficiation process The degree to which an iron ore is processed depends mainly on the iron ore products being made. The most common iron ores on the market are lump ore, sinter fines and iron ore pellets/pellet feed. Which products are suitable for a mine is dictated by the ore's liberation characteristics and market demands.

The first step of physical beneficiation is crushing and grinding the iron ore to its liberation size, the maximum size where individual particles of gangue are separated from the iron minerals. A flow sheet of a typical iron ore crushing and grinding circuit is shown in Figure 1.2.2 (based on Ref. [4]).This type of flow sheet is usually followed when the crude ore …
