Iron Ore Beneficiation. Iron ore is the fourth most common element in earth’s crust. Iron is essential to steel manufacturing and therefore an essential material for global economic development. Iron is also widely used in construction and the manufacturing of vehicles. Most of iron ore resources are composed of metamorphosed banded iron

· The pelletization process is the primary consumer of binders in the iron ore industry. The selection of an appropriate binder type and dosage is of critical importance in producing good quality pellets at a reasonable price. Binders accomplish two very important functions in iron ore pelletization: .

Microbially induced mineral beneficiation involves three strategies, namely, selective bioleaching of the undesirable mineral from an ore or concentrate, selective flotation of the mineral, or selective dispersion/flocculation. Such microbially induced beneficiation will find applications in a number of areas such as: Desulfurization of coals

· At the current rate of GDP growth, this demand will increase and reach up to 300 MT by 2030. Yet, India’s per capita consumption would reach only 160–180 kg (currently approximately 69 kg), which will be lower than the current global average of 208 kg. Hence, to meet the growing steel demand, the demand for iron ore is also increasing.

· By enhancing the quality of lower-grade raw materials through beneficiation, downstream processes also become more viable. Various production routes are available to transform iron ore into liquid steel, as shown in Figure 1. The selected route depends to a large extent on the quality of the iron ore, energy source and related costs.
