Special Issue Information

Dear Colleagues,

More than 70 years ago, V. Vernadsky, who created the holistic doctrine of the Biosphere and the Noosphere, stated that “Humankind is a geological force transforming the face of our planet”. A vast amount of waste (e.g., mining tailing, mine drainage, etc.) has been generated globally during the last century as a result of mining and mineral processing, and this is expected to worsen with increasing resource and energy demand due to increasing population, industrialisation and urbanisation. The high amount of the materials mined or removed for extraction of Cu, Pb, Zn, Pb, Co, Au, Ag, and REE become waste. Therefore, the transition from the existing linear economy (take-make-dispose) to a circular economy in the mining and mineral processing industry (MMPI) is critical and timely. A holistic approach to integrating a circular economy, an alternative model of growth for a sustainable future, includes interconnection and developments in economics, environment, science, technology and innovation, government, society, and education.

This Special Issue is open to (but not limited to) articles related to the following research areas:

  • Strategies adopting a circular economy approach to MMPIs, minimising their negative effects, sharing the best practice, and reducing waste;
  • Mining and Mineral Processing Waste: circular economy solutions;
  • Synergistic solutions, such as industrial symbiosis, for reducing and/or reusing waste;
  • Sustainable materials and processes for valuable element extraction from Mining and Mineral Processing Waste.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

When preparing lightweight ceramsite using carbide slag, trace amounts of toxic elements are released into the atmosphere due to high-temperature calcination, posing a significant risk to the environment. The real-time monitoring of the released gases is challenging under laboratory conditions while preparing large quantities of ceramsite. Therefore, heating was simulated using experimental data and the FactSage 7.0 thermochemical database to study the release of harmful Al-, C-, H-, S-, and F-containing elements when using carbide slag to prepare lightweight ceramsite. The results indicated that no Al, C, H, S, or F elements were evident in the high-temperature liquid products obtained in a 50 °C to 1150 °C calcination temperature range. Al was present in a solid state with no gaseous products. When the temperature reached 450 °C, CO gas was released and its level increased as the temperature rose. H and S mainly combined into H2S gas, starting at 250 °C and reaching a peak at 1050 °C. H and F primarily combined into HF, starting at 400 °C. Other F-containing gases mainly included SiF4 and TiF3, which began to release at 800 °C and 900 °C, respectively. The release trends of HF, SiF4, and TiF3 were consistent with those of CO. This study aimed to conduct an environmental impact and management assessment for the preparation of lightweight ceramsite using carbide slag. The use of raw material carbide slag for the low-cost treatment of tail gas was proposed, which provides theoretical and up-to-date support for greening the application of the process. Full article

With the exploring and developing of mineral resources in the Tibet Autonomous Region for many years, a large number of tailings have been produced. A total of 17 tailings samples from borehole cores were collected from different tailings ponds in different regions of Tibet. The results showed that the mineral composition and content of tailings in each research area were different. Among them, quartz was the most abundant mineral in most tailings. The major elements of tailings mainly included Si, Al, Fe, Mg, Mn, Ca, Na, K and so on. S existed in different types of tailings. In the analysis of trace element composition, it was found that the content of some elements had approached the lowest industrial grade, which has potential recycling value, such as Mn, Zn, Pb and P. Through the detection of radioactive elements (Ra-226, Th-232 and K-40), it was shown that there were great differences among different types of tailings, and their different contents would bring potential hazards to the safety of the surrounding environment and human health. Similar results were found in the analysis of particle size characteristics of tailings. These results are of great significance for the future utilization and resource utilization of tailings pond.
