· Abstract The Ushkatyn-III in Central Kazakhstan is a weakly metamorphosed hydrothermal–sedimentary ore deposit of the Atasu type. For such objects, an assemblage of stratiform bodies of iron–manganese and polymetallic (lead–zinc and barite–lead) ores is typical. At the Ushkatyn-III deposit, there are iron, manganese, and

The iron formation-hosted iron ores are subdivided into unenriched iron formation ores, martite-goethite supergene ores, residual hematite ores and microplaty hematite ores. The three most common iron ore minerals are magnetite (Fe 3 O 4 ), hematite (Fe 2 O 3 ) and goethite (FeOOH), with the most common forms of goethite being brown, yellow

In this study, FTIR spectra were calibrated against quantitative X-ray diffraction data for the determination of the mineralogy of iron ore. A full pattern profiling machine learning technique was utilised for the calibration, and the assessment of the regressions determined from an independent validation set.

Mineral deposit-Iron Ore, Ore Bodies, Mining: By far the most important metal from an economic and technical point of view is iron. Sedimentary iron deposits, from which almost all iron is obtained, can therefore be viewed as one of the world’s great mineral treasures. There are two major types of deposit. The first, and by far the most important, is banded

· The iron minerals that are at present used as ores are hematite, magnetite, limonite, and siderite; also, occasionally ankerite, goethite, and turgite. Hematite is the most important iron ore. The iron content of the pure minerals is as follows: Ankerite is a carbonate of lime, magnesia, manganese, and iron.

· A pressing issue that has often been the topic of discussion in iron-making operations in India is the high content of alumina in the country’s iron ore deposits. The presence of alumina has hampered production by affecting slag fluidity, and thereby the hot metal quality. Iron ores from Indian mines are generally rich in hematite, with traces or

· The target basicity of iron ore sinter is set by blast furnace slag composition requirements, and therefore varies with the proportion of acid burden such as lump iron ore and pellets. Increasing the lump proportion of the burden will increase the target sinter basicity. The mineralogy of sinter produced with a range of basicity
