The articles presented in the first issue of the journal thematically cover all stages of the beneficiation cycle of processing natural raw materials and intermediate products.

In the «Ore preparation» section, you can get acquainted with the results of research by Russian and German scientists, which substantiate the feasibility of using high-pressure grinding rolls in combination with pneumatic classification, which makes it possible to exclude subsequent ball grinding in factories.

The article by Russian and Vietnamese specialists is devoted to the study of quartz-sericite ores of the Ha Tinh deposit. The research carried out made it possible to develop a technology for their beneficiation to obtain a concentrate, the quality of which meets the standards of raw materials for a number of industries.

Depending on the beneficiation schemes and the mineral composition of the ore, the mass fraction of arsenic in the copper concentrates of Uchalinsky GOK can reach 2 %, which significantly reduces their quality. The publication of the section «Вeneficiation processes» presents the process of sulfide-alkaline leaching of flotation copper concentrate, the use of which ensures a high degree of purification from arsenic and compliance of the final product with the requirements of further pyrometallurgical conversion.

Once again, the section «Technological mineralogy» became the most representative in the issue. Its articles propose methods for predicting ore dressability at the early stages of geological exploration. In the work on the study of the composition and properties of serpentinites of the Karmaninsky deposit (Uzbekistan), the possibility of their use not only in its original form, but also as a raw material for the production of magnesium chlorate, used as a defoliant for pre-harvest removal of cotton leaves, is shown.

Thickening and filtration of tailings of concentrating plants are of particular importance in terms of ensuring the environmental safety of production. In the publication on the study of the sedimentation of tailings of the beneficiation of gold-bearing ores from the Yuzhno-Nevyanskoe and Panovskoe deposits, the developed technological modes of the thickening process are presented.

The issue ends with an article devoted to the justification of the use of nonlinear elastic elements as a suspension of the working bodies of vibratory machines with unbalanced vibration exciters. After all, these are the fundamental structural elements of such machines, on which their technological and operational qualities depend.
