“…At the same time, the development of the Arctic territories is one of the most difficult directions in a view of geological features, specific natural and climatic conditions, infrastructure constraints, high level of environmental risks, etc. [6][7][8][9][10]. It is assumed that the Northern eco-systems are fragile and unstable.…”

At present, issues related to the development of rare-earth metal industrial complexes are becoming particularly relevant for Russia. Rare-earth metals (REMs) play a vital role in high technology. Therefore, success in technological progress largely depends on the availability of these metals. However, the country’s position remains uncertain – on the one hand, Russia possesses huge REM reserves, on the other hand, they are not exploited, and the existing level of import dependence of metals on supplies from foreign countries exceeds 80%. The main national REM reserves are in the Arctic region. Nevertheless, even rich deposits are still not exploited. This study aims to investigate the prospects for the development of REM industrial complexes in the Russian Arctic, taking into account both opportunities and constraints. The resource potential of REMs in the Russian Arctic is investigated, a comparative analysis of the characteristics of foreign and national REM objects is provided. The factors influencing the prospects of development of REM industrial raw material complexes are determined. Data on the main REM projects are systematized. The study makes it possible to draw some important conclusions about the current prospects for the development of rare-earth metal industrial raw materials complexes in the Russian Arctic.

“…Among RBEs, Russia provides the biggest and most vivid example of using mineral resources and solving methodological issues in this area [10]. After the collapse of the USSR, the MRD problem became acute in Russia, with its resource portfolio having twentyone weak points, i.e., the supply of these resources did not meet demand [11].…”

Mineral Resource Depletion Assessment: Alternatives, Problems, Results

2021

View full text Add to dashboard Cite

The depletion of non-renewable natural resources (primarily mineral and energy resources) and its assessment is a problem that is analyzed based on the concept of sustainable development. Mineral resource depletion assessment is particularly important for resource-based economies. It provides for assessing the impact of mineral asset disposal that results from the suspension or termination of operations conducted by a mining company due to insurmountable circumstances. The results of such an event will be manifested at the national, regional, and local levels and felt by mining companies, suppliers, workers, the population of the territory, and other stakeholders. The study clarifies the attributes and essence of mineral resource depletion, analyzes the advantages and limitations of the existing tools for assessing mineral resource depletion, identifies depletion factors, describes a methodology for assessing mineral resource depletion, and contains a case study of a tin deposit. The results of the study contribute to the development of the theory on the depletion of non-renewable natural resources. They provide for assessing losses to social wellbeing that can be caused by stopping the use of profitable mineral reserves.

“…The explanation to this is that after aluminium, iron is second most common metal occurring in the earth's crust. Besides that, iron deposits are abundant, relatively easy to access and in most cases are worked by open-cut method; iron smelting process in inexpensive and industry-wide, and iron alloys are processable, meeting the requirements of most industries [1,2].…”

“…Methods of processing for one or another kind of raw material depend primarily on the difference in physical (or physico-chemical) properties of the particles to be separated. The major technique of ferruginous quartzites beneficiation is low intensity magnetic separation (LIMS) [1][2][3][4][5]. The advantages of magnetic methods are minimal environmental footprint, high rate of productivity and relatively low production costs [5].…”
