Promoting the concept and principles of sustainable development at the micro level requires that industrial companies understand and improve approaches to managing corporate sustainability. Currently, economics does not provide a universal definition of what corporate sustainability is. With regard to the mining sector, corporate sustainability issues reflecting the viability, value, and sustainable development potential of companies have not yet been studied extensively. The article discusses the conceptual foundations of corporate sustainability; the characteristics and a classification of approaches to defining corporate sustainability; and the relationship between corporate sustainability, sustainable development at the micro level, and circular economy. By analyzing the example of Russia, the influence of the mining industry on the environmental, economic, and social development of both a country with a resource-based economy and individual mining regions is shown from the viewpoint of sustainability. The distinguishing features of mining companies, which include natural capital and mineral assets, are studied in the context of promoting corporate sustainability. It is proven that the effective corporate management of ESG factors results in environmental and social influence that goes in line with sustainable development requirements and serves as a foundation for corporate sustainability. A refined definition of corporate sustainability has been formulated, the specific features of corporate sustainability management in mining companies have been determined, and the specific features of corporate social responsibility have been studied. The issue of integrating circular economy elements into the corporate sustainability concept is discussed, and it is claimed that the inclusion of circular business models in the corporate strategies of mining companies will contribute to their corporate sustainable development and boost their contribution to the achievement of sustainable development goals.

The actively developing concept of a circular economy affects directly the interests of mining companies. The analysis shows that the potential impact of the circular economy on the solid mineral mining sector is contradictory, and the productive capabilities of the circular economy within the sector are not completely clear. At the same time, the question of transition from a linear model to a circular model of using material resources has been entered on the global economic agenda in the context of sustainable production and consumption. The aim of this study is to disclose the modern concept of the circular economy, its impact on the sector of solid mineral mining and processing, and its capabilities within the sector. The analysis shows that the economy, which is based on the model of closed (circular) supply chains in the industrial production cycle, represents constitutes simultaneously a threat to mining companies and brings incentives for their technological development. Such a duality is caused by the fact that the implementation of the idea of replacing natural resources by secondary material resources by extending life cycle of materials and minimizing waste returned to the environment requires increasing manufacturability of industrial production. The decrease in the share of primary resources in production cycles does not fit well with the corporate strategies of mining companies aimed at expanding mining to meet the growing demand for the final products of mineral mining and processing. The study shows that the use of the adapted circular business models in mining and processing of mineral raw materials can become a driver of technological upgrading of mines, an incentive for involving accumulated waste in business circulation, while ignoring it threatens the mines with a loss of strategic competitiveness. The comparison of the concepts of the circular economy and the best available technologies (BAT) leads to the conclusion that the “circularity” contributes to introduction of BAT, increasing sustainability of mines and of the whole industry in the face of a growing uncertainty. Recognition of these concepts as a positive factor may trigger the mechanism of institutional support for the transition of mining companies to a next technological level against the background of decreasing quality of natural mineral raw materials and worsening conditions for their extraction.
