Iron ore beneficiation: an overview ScienceDirect
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 Being different from iron ores, most nonferrous metal ores are low grade, with metals in the forms of complex mixtures of sulfides, oxides, carbonates, and silicates. Therefore, to be economically extracted, nonferrous metal ores are normally concentrated by mineral beneficiation to separate the metal from waste rock prior to the extraction steps.Beneficiation (Metallurgy) an overview ScienceDirect Topics

It may also contain other elements or minerals as impurities, such as silica, alumina, phosphorus, sulfur, and trace elements.

The current study investigates the beneficiation of iron ore fines by the carbothermal process using muffle and microwave furnace. The muffle furnace reduction was found useful for the separationThe blast furnace and direct reduction processes have been the major iron production routes for various iron ores (i.e. goethite, hematite, magnetite, maghemite, siderite, etc.) in the past few decades, but the challenges of maintaining the iron and steel-making processes are enormous.

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 appliedThough the country can boast of huge good quality iron ore resources, the percentage of reserves to total resources is quite dismal as only 5,422 million tonnes (24%) of haematite and mere 53 million tonnes (0.49%) of magnetite resources are categorised as reserves as on 1.4.2015 as per UNFC categorisation.

Advances in Beneficiation of Low-Grade Bauxite SpringerLink
In low-grade ores and run-of-mine (ROM), minerals are mostly associated with different impurities in the bauxite . The major impurities present in bauxite are silicon,iron oxides, and calcium, which introduces processing problems that can affect its utilizations in ceramics, abrasives and refractories [].Removal of these mineral impurities The processing of oxide and mixed ores is minimal. The aim of this paper is to review the published papers on the flotation of copper ore with reference to different mineralogy and recently developed pretreatment methods to intensify the separation.

Iron Ore ScienceDirect
Abstract. Iron ore is regarded as the second most important commodity behind oil. As an essential input for the production of crude steel, iron ore feeds the world’s largest trillion-dollar-a-year metal market and is the backbone of global infrastructure. To meet the growing demand for steel products, world iron ore production has increasedUsing selective flocculation, the grade of an iron ore was increased from 44.4 to 50% with a 69% recovery in the <20 mu m fraction; ash content of coal was decreased to 30.5% with a 52.5% coalBeneficiation of iron ore washing with surface-active agent
