Iron is also widely used in construction and the manufacturing of vehicles. Most of iron ore resources are composed of metamorphosed banded iron formations (BIF) in which iron is commonly found in the form of oxides, hydroxides and to a lesser extent carbonates.

Limonite is one of the main iron minerals. It is a brown natural multimineral mixture based on hydrous iron oxide. But its iron content is not high, it is a secondary iron ore. Beneficiation Process
What Is Iron Ore Beneficiation? (with pictures)
Oct 26, 20190183;32;Iron ore beneficiation is a multistage process that raw iron ore undergoes to purify it prior to the process of smelting, which involves melting the ore to remove the metal content. The process of iron ore beneficiation has two complementary goals and these define the methods used to refine it.
The two main methods of recycling iron from iron ore tailings are magnetizing roasting and direct reduction. Magnetizing roasting uses temperatures between 700 and 900 176;C for a time of under 1 hour to produce an iron concentrate (Fe 3 O 4) to be used for iron smelting.
The Beneficiation Techniques for 5 Types of Iron Ores in
According to the weakness, the professionals create a new limonite beneficiation technique, which can improve the iron ore grade effectively, and the steps are as follows Limonite iron ore processing method. Crushing and grinding
NamesLimonite is an iron ore consisting of a mixture of hydrated iron oxidehydroxides in varying composition. The generic formula is frequently written as FeO(OH)183;nH2O, although this is not entirely accurate as the ratio of oxide to hydroxide can vary quite widely. Limonite is one of the three principal iron ores, the others being hematite and magnetite, and has been mined for the production of iron since at least 2500 BCE.
Limonite Ore Processing ProcessOre Beneficiation
Limonite beneficiation process Processed ore by mine plant is red iron hard rock, main iron minerals are martite, half martite, gangue minerals are quartz, secondly are amphibole, chlorite,etc. Ore shows obvious banded structure, disseminated size is finer, martite and quartz granularity are generally 0.020.2mm, the ore should be grinded to 200 mesh 80% g/t, formulated 20% aqueous solution, by adding
