Bauxite residue, known as red mud, is a by-product of alumina production using the Bayer process. Currently, its total global storage amounts to over 4.6 billion tons, including about 600 million tons in Russia. The total global storage of red mud occupies large areas, leading to environmental damage and increasing environmental risks. Moreover, it contains a significant amount of sodium, which is easily soluble in subsoil water; therefore, a sustainable approach for comprehensive recycling of red mud is necessary. The bauxite residue contains valuable elements, such as aluminum, titanium, and scandium, which can be recovered using liquid media. In recent years, many methods of recovery of these elements from this waste have been proposed. This paper provides a critical review of hydrometallurgical, solvometallurgical, and complex methods for the recovery of valuable components from red mud, namely, aluminum, titanium, sodium, and rare and rare-earth elements. These methods include leaching using alkaline or acid solutions, ionic liquids, and biological organisms, in addition to red mud leaching solutions by extraction and sorption methods. Advantages and disadvantages of these processes in terms of their environmental impact are discussed.

Há uma frase que diz: "A gratidão transforma o pouco que temos, em suficiente". É incrível o quanto ela representa minhas crenças e minha alegria em compartilhar a vida com tanta gente boa, sou grata! Primeiramente, sou grata a Deus por ser a força motriz da minha vida, da minha existência, por conduzir meus passos e principalmente por ter me dado uma família valiosa, cheia de princípios, amor, carinho, cuidado, que me ensinou e incentivou a sonhar. Família, obrigada por serem tudo o que são! Amo vocês! Agradeço também a todos os meus amigos, de trabalho, mestrado, graduação, república, vocês são tantos e tão valiosos, que jamais me atreveria a nomear cada um. Vocês são e sabem que são! São os que me incentivam a continuar, me fazem rir, são colo, abrigo e morada.Obrigada por me incentivarem a ser cada dia melhor. Obrigada por tanto!!! Essa pesquisa só foi possível graças à orientadora incrível que tive/tenho da Professora Doutora Maria Lúcia Pereira Antunes (Malu) e pela ajuda no esclarecimento de dúvidas do Professor Doutor Fabiano Tomazini, muito obrigada pela orientação, paciência, carinho e parceria. Ao Professor José António da Silva Souza (UFPA), por nos ceder as amostras de lama vermelha do Pará.
