Iron ore crushers and other machines. There are several ways to extract iron ore from rock. Here is a basic flow chart outlining the steps involved in the production of iron from iron ore: MiningIron ore mining methods vary by the type of ore being mined. Currently, there are four main types of iron ore deposits, depending on the mineralogy and geology of the ore deposits. These are magnetite, titanomagnetite, massive hematite, and piso-litic ironstone deposits. For taconite iron ores, mining iron ore begins at ground level.Iron Ore Processing, General

Iron and some alloys of iron are also magnetic. Iron is about eight times heavier than water (its relative density is 7.87). When iron is exposed to air it starts to turn back into iron oxide and the red powder that forms on the surface of iron is what we call rust. You may have seen rust on old cars or old iron sheds.The haematite ore in South Africa is processed in a dry process to a HQ lump ore with 64 % iron content and a sintered fine ore with 63.5 % iron content. For fine ore beneficiation, wet processes are used. Capacity at the Minas Rio is to be increased from 26.5 Mta capacity to 28 Mta in the forthcoming years.Dry beneficiation of iron ore Mineral Processing

2.4. Beneficiation methods. Beneficiation is a process where ore is reduced in size and valuable minerals are separated from the gangue minerals. Separation of valuable minerals from gangue minerals can be efficiently achieved by taking advantage of the differences in physical, surface, and magnetic properties.Iron ore handling, which may account for 20–50% of the total delivered cost of raw materials, covers the processes of transportation, storage, feeding, and washing of the ore en route to or during its various stages of treatment in the mill..

Iron ore beneficiation can be brought about through three approaches, namely, selective dissolution, microbially induced flotation, and selective flocculation–dispersion. The bioprocesses are specially suited to treat fines, slimes, and waste tailings. 4. Potential applications include.For iron ores with significant amounts of rare-earths [47,[320][321][322][323] [324] [325], the incorporation of rare-earth recovery steps can improve the economy of the ore beneficiation processProcess flow diagram of Chadormalu Iron ore

11.23.2 Process Description2-5,41 Processing of taconite consists of crushing and grinding the ore to liberate iron-bearing particles, concentrating the ore by separating the particles from the waste material (gangue), and pelletizing the iron ore concentrate. A simplified flow diagram of these processing steps is shown in Figure 11.23-1.
