The current resource production paradigm supports large-scale and low-grade mining of world-class ore deposits. Global financing models are not suited to the extraction of the specialist metals required in small quantities for technological innovation, because it will not generate a large enough return. A diversity of mining solutions is required that continue to scale up extraction for bulk metals, find new mechanisms for by-product recovery, or facilitate extraction of technology metals from small-scale and high-grade ore deposits. However, in all cases, mining must operate to minimise negative environmental, social and economic impacts, to reduce waste, energy and water consumption.
The IMP@CT project proposes a solution that develops a new switch on-switch off (SOSO) mining paradigm to improve the viability of small complex ore deposits. Our whole systems approach centres around technological innovations in mining equipment design and mine planning that would reduce the feasibility studies required, throughput of extracted material, infrastructure, land use, resource consumption and waste. Successful business models for SOSO mining require that mining and processing technologies can be adapted to multiple deposits and commodities. Risks that are associated with the approach concern geological uncertainty, metallurgical variability and social acceptance. Our overall objectives were to demonstrate that the concept of SOSO mining is viable using case studies in the West Balkans, and to understand the wider settings in which it can work in Europe.
The entire mining system produced lead concentrate in Bosnia and Herzegovina, at the Olovo mine site and then antimony concentrate from an ore deposit in Serbia, in a way that is conductive to low carbon production, environmental management and low impact on society.
