This chapter briefly discusses the current scenario of the iron ore resources in India, iron ore mining methodology, beneficiation technique, and the current operating The quality of Indian iron ore resources is generally good with high iron content and high percentage of lumpy ore. More than 85% of the hematite ore reserves are of medium- to high-grade (+62% Fe) and are directly used in blast furnace and in direct-reduced iron (DRI) plants in the form of sized lump ore, agglomerated sinter, and Iron ore beneficiation: an overview ScienceDirect

Research regarding iron ore flotation began in 1931, demonstrating that reverse cationic flotation is a very efficient method for beneficiating oxidised iron ores. This method can also be appliedGeology, deposit types, and ore minerals. There are more than 200 minerals that contain REE. 7,8 The most common rare-earth minerals are monazite and bastnäsite (Figure 1a–b and Table II).Monazite exists as a group of arsenates, phosphates, and silicates, but the primary REE-bearing monazite is a complex phosphate. 5 Processing the ores of rare-earth elements SpringerLink

Beneficiation of Clay-Rich High-LOI Low-Grade Iron Ore
The unutilized iron ore fines (IOF, − 10 mm, 45% to < 60% Fe(T)) left at various mine sites during blasting and processing are rich in goethetic-hematite associated with high clay and considered a potential iron ore resource. The variation of loss on ignition (LOI) from mines to mines is based on the goethite and clay mineral content. The clay The applications and utilization of Nb and Ta materials by industries is greatly dependent on the purity-impurity level of the final products [3].In essence, the production of high purity Nb/Ta metals from mineral resources as well as the choice or application variation depends on the mineral type (ore or concentrate), nature, quality Factors and challenges in the recovery of niobium and

Reserves and Resources of Iron Ores of India — A Perspective
With a total resource of 22,487 million tonnes of haematite (Fe2O3) and 10,789 million tonnes of magnetite (Fe3O4), India ranks seventh among the countries to possess abundant iron ore resources, in the world. India is not only one of the leading producers of iron ore but also at present second largest manufacturer of steel in the The presence of appreciable quantity of clay mineral in Indian hematite ore needs an attrition technique using screw scrubber in the beneficiation circuit to remove the ultrafine clays and avoid downstream operational problems.
