iron ore is expected to rise by more than 200 million tonne per year to meet the internal demand export. This additional requirement of iron ore will need beneficiation of low grade ore/fines to get the major portion of increased demand. This paper deals in brief to use of available methodologies for beneficiation of iron ore in Indian context.

Introduction. Hematite and magnetite iron ores are the most prominent raw materials for iron and steel production. Most of the highgrade hematite iron ores are typically subjected to simple dry processes of crushing and classification to meet the size specifications required for direct shipping ore (DSO).

The lithium beneficiation process is mainly used for three lithiumcontaining minerals processing: spodumene, lithium feldspar, lepidolite. Lithium ore beneficiation is mainly based on flotation process. It is also often combined with gravity separation, magnetic separation and other combined processes. Gravity separation: 1.

Rough processing of iron ore employs dry methods which means that equipment is tuned to process large particles, but fine magnetic material less than a few tenths of a millimeter in size is not separated as efficiently. The relevance of this study is determined by the fact that dry beneficiation waste contains recoverable ironbearing magnetite of commercial value.

Development of dry magnetic separators. Most iron ore processing takes place in the fine particle size ranges and is often carried out on a wet basis. However, some iron ore resources are located in dry areas where adequate water supply is very difficult to obtain and hence dry processing is the only option.

Till now, majority of studies on processing and beneficiation of feldspar ore focused on removal of those phases which are considered as harmful colouring admixtures in ceramic/glass industries [44,45,46,47]. In order to make the beneficiation process effective and economic, any Fe, Ti or Mnbearing phase is considered as harmful.

Figure 3 shows a comparison of the IEA and WSD views and the related iron ore demand of between 400 and 600 mt by 2050, compared to about 160 mt in 2019. From the quantitative perspective, iron ore supply should not be an issue, with BF iron production falling from just under billion tonnes in 2019 to 665 mt by 2050 per IEA's SDS (see Figure 1).

Beneficiation. Mineral beneficiation begins with crushing and grinding of mined ore for nearcomplete separation of ore and gangue minerals as well as between ore minerals. Each processing step is designed to increase the grade (concentration) of the valuable components of the original ore.

Iron Ore Beneficiation Process Flow. One popular beneficiation method is mechanical crushing and screening, which involves breaking down large chunks of ore into smaller pieces and separating them based on size. This method is particularly effective for lowgrade ores where the iron content is not very high.

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 (based on Ref. [4]).This type of flow sheet is usually followed when the crude ore contains below 30% iron.
