“…Essential reserves of such ores ore located in Krivoy Rog iron ore basin (Ukraine) and in Russia, where the main part of iron ore reserves (59 %) is concentrated in Kursk magnetic anomaly (KMA). Mikhailovskiy and Lebedinskiy mining and concentrating plants, which are incorporated in "Metalloinvest" company, occupy the leading places in iron ore mining and concentrate production [1][2][3][4][5].…”

The paper presents the review of the main technologies for concentration of rich iron ores and factors having influence on selection of the technology and concentration parameters. The most important technological parameters at the leading concentration plants (both abroad and in Russia), which are processing rich iron ores, are observed. It is shown that even ores with Fe content more than 65 % are subjected to concentration abroad. At present time, only 15 % of iron ores in CIS can be directed to metallurgical processing without concentration, 65 % of iron ores are concentrated via simple routes, but 20 % of iron ores require use of combined concentration methods. The aim of this work was study of substantial composition of large-lump hematite ore at Mikhailovskoe deposit and determination of possible technological pre-concentration methods for rise of Fe content in sinter ore up to 53-55 %. Examination of mineral composition of grab and bulk samples displayed that oxidized ferriferous quartzites are characterized by thin-layered texture with alteration of ore-free layers and interlayers, which are enriched by hematite. Coarseness less than 2 mm for more than 45 % of material proved presence of essential amount of slightly structured mineral differences and high oxidation degree. The experiments on determination of possibility of technological preliminary concentration of large-piece rich hematite ore were carried out using gravitation, X-ray absorption (XRT) and electromagnetic (EM) methods, dry magnetic separation in weak and strong field. It was shown that preliminary concentration of large-piece rich hematite ore from Mikhailovskoe deposit is impossible due to the features of mineral composition (wide range of porosity of ore lumps, Fe content outside the ranges of XRT method use, presence of essential amount of martite with relict magnetite nuclei etc.).

“…The main reserves of oxidized nickel ores are found in the Kempirsai group of silicate deposits located in the Aktobe region of the western part of Kazakhstan. At the moment, the total reserve of nickel ores in Kazakhstan is ~423.5 million tons [6]. However, the main reserves of nickel ores are substandard.…”

The article presents the results of obtaining a composite material by sintering nickel-containing raw materials mixed with carbon-containing materials, namely using coke and semi-coke. The sintering process was performed at a charge layer height of 240 mm and the temperature of the lower layer was T = 1200 °C. The results of the sieve analysis showed (a fraction of 10 mm) that the yield of a suitable composite material using coke was 68.3% and with semi-coke 67.0%. The average nickel and chromium content in the composite materials was 1.42% and 3.07%, accordingly. As a result of determining the strength characteristics of the obtained composite materials with various reducing agents by dropping from a height of 2 m onto a steel pallet, it was found that the obtained composite materials have high mechanical properties in terms of strength of 81% and 89.2%. The results of the elemental composition at the studied points and the thermal analysis of the studied composite material are presented. The mineralogical composition of the composite material is presented in the form of serpentine and nontronite, and the empty rock is made of quartz and talc. The activation energy of thermal analysis by the method of non-isothermal kinetics were calculated. The results of experiments on the production of composite materials from nickel-containing raw materials will be recommended for obtaining the optimal composition of composite materials at the stage of pilot tests and industrial development of the developed technology for processing nickel ores of the Republic of Kazakhstan. For the processing of nickel-poor nickel ores, it is of great importance to obtain optimal technological and technical and economic indicators that ensure low cost of nickel in the resulting product.
