“…The increasing interest in red mud has led to a significant number of publications and researchers working in the field in recent years, due to concerns about the high volume of residues. As a result, more applications and areas of study are being explored, leading to a high level of specialization and a high amount of literature [ 6 , 12 , 20 , [25] , [26] , [27] , [28] , [29] , [30] ]. Although there are various specialized reviews of the state of the art of red mud available in the literature, these reviews mainly analyse specific aspects, such as applications.…”

“…[2][3][4] Because of its excellent properties, it is strategically significant for aerospace and military fields. 5 However, its distribution is highly dispersed, and it is often associated with bauxite, scandium manganese tantalum, rare earth ore, and other minerals; 6 therefore, it is difficult to separate and produce highly pure scandium. Therefore, it is a scarce and expensive metal, and thus, it is of great research value to separate and recover scandium.…”

“…A extração de bauxita apresenta como característica principal a mineração de superfície, que consiste na remoção da camada superficial do solo (Chen et al, 2022). Para que a exploração de bauxita seja viabilizada, faz-se necessário remover a vegetação e as camadas superficiais do solo, denominadas como topsoil, região onde é encontrada a maior concentração de nutrientes e matéria orgânica do solo.…”

“…Para minimizar e/ou evitar os impactos negativos da atividade minerária é necessário estabelecer um sistema de reabilitação ambiental sustentável, através de técnicas que visem à manutenção e a melhoria da qualidade ambiental, de forma a reestabelecer o equilíbrio dinâmico das áreas mineradas, a fim de que as áreas que passaram pelo processo de extração da bauxita sejam devolvidas ao seu proprietário em condições produtivas seguras e ambientalmente estáveis, de forma a integrar novamente a área perturbada ao ecossistema natural (Chen et al, 2022).…”
