Special Issue Information

Dear Colleagues,

The establishment of a sustainable supply chain for raw materials is among the most emerging priorities in modern societies. The majority of critical and valuable raw materials with direct impact in renewable energy generation, high-technology applications, and industrial processes are those produced by mining activities. As a traditional economy sector, metal and mineral exploration and processing meets many challenges in adopting a new approach toward environmental neutrality, the optimization of energy, the efficient use of resources, and circular economy practices and approaches. In particular, the fields of interest involve the design of novel mining and metallurgical processes, new methods for mineral exploration, incorporation of digital technologies, exploitation of secondary products or wastes through innovative products, end-of-life recycling, and long-term environmental safety.

In this context, the aim of this Special Issue is to collect new ideas on the possible engagement of mining and metallurgical processes with sustainability development goals through evidence derived by high-impact research studies and assessment approaches. Moreover, in this Special Issue, we aspire to present a selection of original and innovative papers highlighting the most challenging aspects relating to the comprehensive integration of life cycle thinking in mining and metallurgical processes. Concepts, challenges, perspectives, and opportunities will shed light on the dynamic and forward-looking nature of environmental impact assessment tools especially in light of the sustainable development goals and the priorities of raw materials in the circular economy. Successful paradigms of environmental impact assessment methodology and LCA application on specific case studies in the mining and metallurgical industry are also welcomed.

The Special Issue will also welcome selected papers on related topics from “The International Conference on Raw Materials and Circular Economy” (RawMat2021, www.rawmat2021.gr).

The conditions of declining gold grade in the ore, increasing depth of excavation, and de-creasing unallocated stock of deposits make it necessary to develop efficient solutions for the mine-to-mill process, which have to be adapted to each specific mining plant and will optimizes production costs. Current research focuses on a case study that demonstrates how indicators of mining losses and dilution influence the variation of costs chain in the production cycle. The article examines the topical issue of determining the effects at the mine-to-mill stages due to changes in losses and dilution. The author’s approach to the formation of a mine-to-mill cost chain is proposed by integrating several cost estimation methods into the general cost estimation methodology. The estimation methodology is a compilation of factor analysis and cost engineering methods that take into account the change in costs due to the variation of losses and dilution. It was proven that with variations in losses and dilution, cost savings arise due to changes in the volume of work on ore averaging, ore transportation, and beneficiation. For the case of the Kuranakh ore field, there are no effects at the mining stage. The use of internal reserves by means of managing ore quality parameters allows reducing the costs per ton of processed rock mass along the entire production chain. Full article
