“…Therefore, an extremely strict waste management policy must be employed to mitigate the damage caused by the niobium mining and processing industries, especially due to the potential radiological hazard of the waste. A long-term prediction of non-processed waste radioactivity of the Catalão mine has been developed, and radiological hazard indices found were higher than the reference values or the global average (El Hajj et al, 2019). This fact raises some important concerns since the Brazilian authorities have shown special interest in Nb mining.…”

“…In Brazil, the majority of the population perceives the mineral sector as having a significant environmental impact (Oliveira Cruz and da Cunha Rodovalho 2019), especially after the recent collapse of two tailings dams. Therefore, the mining sector is seeking new exploitation technologies to minimise its environmental impact, such as reducing the tailings by separating the coarse grained particles (Shouhouhi and Williams 2017), while meeting market demand (El Hajj et al 2019; Brandao Gomes et al 2015; Stohard and Laurence 2014; da Cunha Rodovalho and Eyer Cabral 2014). Bauxite mines usually store the waste as construction material for safety berms, reshaping the terrain and for haul road maintenance.…”
