“…However, only a small part of the nepheline concentrate is used for the production of alumina, the rest is practically not used in the production (Sizyakov & Brichkin, 2018;Elbendary et al, 2019;Ponomarenko et al, 2021). To date, about 1 billion tons of nepheline-containing waste have accumulated in the dumps of enrichment plants, and annually they are replenished in the amount of 15-20 million tons (Siziakova et al, 2019;Chukaeva & Matveeva, 2018;Sizyakov et al, 2020).…”

The article presented the results of studies on the production of low-modulus zeolites from two types of technogenic resources containing a sufficient amount of silicon in their composition. The raw materials were nepheline concentrate and silica gel, which are products of the processing of apatite-nepheline ore. Directly before the synthesis of low-modulus zeolites, the morphology, chemical composition, and particle size of the starting materials were analyzed. The optimal parameters for sample preparation and purification of the raw materials used were also selected. The influence of the ratio of components in the reaction mixture on the type of synthesized zeolite and its characteristics were studied. The properties of synthesized zeolites from the proposed type of raw material were compared with the properties of zeolites synthesized today using the popular technology from kaolin clay, which is currently offered as an inexpensive natural raw material.

“…It is often necessary to quantitatively determine the impurities of heavy metals and rock-forming elements in materials of various nature, without directly destructing them. − A certain approach is required when working with carbon-based materials. − Most often, in this case, one has to deal with soot, graphite, − nanotubes, petroleum cokes, and coals. − Typical values of the content of trace elements in carbon materials of various types are in limits 10–1500 ppm …”

Quantitative Determination of Trace Heavy Metals and Selected Rock-Forming Elements in Porous Carbon Materials by the X-ray Fluorescence Method

A new X-ray fluorescence (XRF) method is proposed for sample preparation and impurity quantification for elements heavier than sodium in carbon materials. The analysis is suitable for various materials including amorphous ones, such as petroleum cokes, with an impurity content higher than 0.01%. We compared a new method with the regular additive method to measure impurities in electrode graphite and petroleum coke. The XRF-based method provides the same sensitivity and accuracy and much greater reproducibility of the analysis results for variations in the sample mass, its density, and coverage by exciting X-ray radiation. The method does not require changes in the instrument software and is easily implemented on commercial analytical equipment.

“…Research and calculations which are made by different laboratories in the world, shows us the principal possibility to work off and complex rework ferrous tailings. But we may ascertay that fundamental switching over principles of transiting to the low-waste technologies, which can promote developing minerals fields through technological fields formation, and also development of current technological formations [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29].…”

The inevitable depletion of mineral resources, the constant deterioration of the geological and mining conditions for the development of mineral deposits and the restoration of raw materials from mining waste by recycling are all urgent problems we faced today. The solution to this problem may ensure: a considerable extension of raw material source; decrease of investments in opening new deposits; cost savings for dumping and handling of tailing dumps, disturbed land remediation; obtaining social and economic effect due to a considerable reduction in pollution of the environment. This article deals with the study of iron-containing tailings dumped at the tailing dumps of ore-refinery and processing facilities located in Kursk Magnetic Anomaly (KMA GOKs), where samples were taken for this study. The article contains the results of the materials composition study, namely: chemical composition, the mineralpetrographic study of thin and polished sections, grain size distribution and physical-mechanical properties of tailing samples. Regularities were revealed for the change of the useful component content due to gravity differentiation. It was also noted that the sulphur content increased near the pulp discharge outlet due to pyrite accumulation. The ratio of ore minerals in tailings and the fineness ratio of the sand fraction were measured. The examination with a focused beam microscope with x90 to x600 magnification showed a variety of grain sizes and shapes that facilitate using tailing materials after additional processing in the construction industry as sand.
