Heavy metals and metalloids (HMMs). Is it possible to “green” utilization of man-made waste?

The contamination of natural ecosystems with heavy metals and metalloids (HMMs) primarily results from anthropogenic activities. Consequently, ongoing efforts are dedicated to the development of technologies aimed at restraining the mobility of HMMs and expediting chemical reactions that convert pollutants from mobile to immobile states. In terms of performance and future potential, the sorbent-oriented approach, grounded in the concept of “green” utilization of man-made waste as a raw material for creating novel composite sorbents, is gaining traction for land reclamation in disturbed areas.
The conducted experiments revealed that sorbents composed of peat/water treatment sludge (at a ratio of 20/80 wt. % with natural moisture content) and peat/diatomite/water treatment sludge (at a ratio of 5/15/80 wt. % with natural moisture content) exhibited the highest level of performance, surpassing an overall efficiency of 89%.

We present the articles of the third issue of scientific journal "Mining Science and Technology” (Russia) for 2024:

This paper presents data on the assessment of the readiness of auxiliary mine rescue teams in Russian coal mines. A survey of professional mine rescuers was conducted across all units and platoons, focusing on key aspects of auxiliary team operations. The results, based on expert evaluations, revealed the main challenges in training auxiliary team members and highlighted areas for improving the regulatory and methodological framework for mine rescue tactics.

What are the environmental consequences of mining operations in Arctic regions?

The problems of geoenvironmental consequences of mining operations are especially acute in the arctic and subarctic regions, where the spread of permafrost significantly reduces the buffering capacity of landscapes. The research, the results of which are published in the journal Mining Science and Technology, demonstrates data on the content of heavy metals in the soil cover of the transient zone between the middle taiga and north taiga landscapes of Western Yakutia under the conditions of mining operations. The authors proposed new approaches to evaluation assesses the resistance of different types of soils to heavy metals pollution. The heavy metals content was determined by atomic absorption spectrometry. Among the studied pollutants the greatest tendency to binding by natural organic ligands was revealed for such elements as lead and copper. Zinc and nickel will actively migrate in the ionic form. Cadmium occupies an intermediate position in terms of the ratio of ionic and organically bound forms. The data presented in the study can be used in monitoring the state of the soil cover in the mining zone.
