The chemical and phase composition of iron-manganese rare-earth ores of the Tomtor deposit were investigated. It is shown that the ores contain a large amount of iron, manganese and rare earth metals. The thermodynamic calculation of reduction smelting was carried out. The reduction smelting of the ores at 1650 °C was investigated. The phase and chemical composition of the obtained slag and the alloy were studied. It is showed that obtained alloy is ferromanganese with a high content of carbon and phosphorus, and obtained slag has high content of REM.

Diffusion Redistribution

The transformation of the structure, phase and chemical composition of the diffusion coatings of the system Al-Ni and Al-Cr-Ni at 1100 °C is studied. It is shown that the diffusion redistribution of Al by the coating thickness during the heat treatment is slower in the system Al-Cr-Ni than in the binary system Al-Ni.

Alumina Industry

Red mud is a by-product of alumina industry which is currently almost completely stored in landfill sites without further use. It contains considerable amounts of valuable components such as iron, aluminum, titanium and rare-earth metals. The reduction smelting of red mud was carried out in laboratory scale to recover iron and obtain slag suitable for use in the construction industry. It has been shown that it is expedient to obtain pig iron and slag from the unprocessed red mud. Those two are suitable for the subsequent leaching of aluminum, titanium and rare-earth metals. It is practical to process dealkalized red mud, with composition adjustment by CaO and Al2O3 addition, in order to obtain pig iron and slag in the form of aluminous clinker.

2205 Duplex Stainless Steel

The effect of rare earth metals on modifying inclusions of 2205 duplex stainless steel was studied by metallographic examination, SEM and electron spectroscopy. Thermodynamic calculation was used to analyze the formation of RE inclusions in 2205 duplex stainless steel. According to the composition of 2205 duplex stainless steel liquid and thermodynamic data, it may calculate and predict the kinds of RE inclusions. And the result shows that aluminosilicate complex inclusion and sulfide inclusion can be entirely replaced by RE2O2S and RES that are spherical.
