“…Another interesting work 503 is presented by Memarya et al[74], where LCA is applied to estimate impacts from the 504 five largest Australian copper mines, incorporating changes in ore grade and differences in 505 technologies and regional energy sources. Annualized results from years of copper produc-506 tion suggest the importance of considering time-series-based LCA models to assess future 507 technology and energy options in the mineral sector.…”

“…Furthermore, uranium can be recovered from copper mine tailings as for instance discussed by Chmielewski et al [92]. Copper production, especially pyrometallurgical copper production, is an energy intensive process [93,94]. HTRs do not reach the high temperatures required to deliver process heat for the smelting step.…”

A number of primary ores such as phosphate rock, gold-, copper-and rare earth ores contain considerable amounts of accompanying uranium and other critical materials. Energy neutral mineral processing is the extraction of unconventional uranium during primary ore processing to use it, after enrichment and fuel production, to generate greenhouse gas lean energy in a nuclear reactor. Energy neutrality is reached if the energy produced from the extracted uranium is equal to or larger than the energy required for primary ore processing, uranium extraction, -conversion, -enrichment and -fuel production. This work discusses the sustainability of energy neutral mineral processing and provides an overview of the current progress of a multinational research project on that topic conducted under the umbrella of the International Atomic Energy Agency.

“…É claro que o fator de emissão associado à eletricidade depende fortemente do tipo de fonte energética empregada e também da localização da operação. Ainda mais, são encontradas diferenças significativas na matriz energética entre diferentes estados ou regiões de um país, como pode ser observado no trabalho de Memary et al [10]. Segura e Tavares [9] Assim, existem fatores chave que devem ser considerados do ponto de vista da ecoeficiência, especialmente durante o projeto de uma nova usina.…”

ResumoAlgumas estratégias vêm sendo incorporadas na cominuição de minérios, voltadas para reduzir os custos operacionais (OPEX) e garantir o funcionamento de suas operações no longo prazo. Paralelamente, elas permitem reduzir os impactos ambientais desta operação sob a ótica da sustentabilidade, devido às melhorias na eficiência de uso dos recursos e na mitigação das mudanças climáticas. Porém, a incorporação dessas estratégias é restrita pelo tipo de tecnologia empregada e pelo layout da usina e, portanto, o maior potencial de minimização dos impactos econômicos e ambientais encontra-se principalmente na etapa de projeto dos circuitos. Este potencial muitas vezes é desperdiçado, sendo ainda poucas as implementações sistemáticas adotadas na indústria mineral, visando melhorar a ecoeficiência dos processos. Neste trabalho é proposta uma metodologia fundamentada em princípios de sustentabilidade e aplicável ao beneficiamento de minérios, usando uma abordagem simplificada da Avaliação de Ciclo de Vida (ACV). A metodologia é focada na cominuição de minérios brasileiros, tendo sido aplicada ao beneficiamento de Itabiritos, os quais estão se tornando estratégicos no Brasil.

ECO-EFFICIENCY IN THE DESIGN OF COMMINUTION CIRCUITS: THE BRAZILIAN CASE STUDY AbstractA number of strategies are being incorporated in the comminution of ores in order to ensure the functioning of its operations in the long term, mainly focused on reducing operating costs (OPEX). In addition, these strategies support the minimization of environmental impacts in comminution operations from the sustainability standpoint, due to improvements in the resource use efficiency, as well as in climate change mitigation. However, the adoption of these principles is restricted by the type of technology used and by the plant layout. Therefore, the greatest opportunity in minimizing these economic and environmental impacts is primarily in the plant design stage. In spite of this potential, only a few experiences and systematic implementations based on eco-efficiency principles have been undertaken in the minerals industry. The present paper proposes a methodology based on sustainability principles applied to beneficiation operations, using a simplified Life Cycle Assessment (LCA) approach. The proposed methodology has emphasis on comminution of Brazilian ores, having been applied to itabirite iron ores, whose beneficiation is becoming strategic for current and future projects in Brazil.
