“…Electro migration was used to recover 99.9% tin with a lead cathode, a tin anode and hydrogen chloride electrolyte (Gergo et al 2012). A laboratory experiment which used a tin anode, an iron cathode and hydrogen chloride electrolyte yielded a low 9% recovery (Jumari et al 2018). The type of electrodes has a significant bearing on the amount of material recovered.…”

Water is employed as a cost-effective media of transporting tailings; a mixture of ground waste ore, water and chemicals used in metal extraction processes. Tailings are conveyed in pipelines from the plant to the tailings dam. From the dam, the water should be recycled back to the processing plant but herein lies the challenge. The hydraulic conductivity of fine-grained tailings is very low such that instead of draining, the water tends to accumulate in the dam. Not only does this led to pore water pressure build up which undermines the dam's stability, but it also causes massive water losses by evaporation more so in arid regions. Dewatering of tailings prior to disposal has emerged as a solution that can be used to conserve water by producing paste or thickened tailings. Thickened tailings have higher shear strength, lower volume and they reduce dam closure costs. Filtered tailings can also be used as underground backfill for mine cavities or transported with conveyor belts and trucks to a designated point. The main limitation is that the benefits of dewatering are mainly technical and they do not yield a direct financial return. Processes that increase mineral production are vital in mine operations. Apart from the residue of the targeted metal, most tailings contain base metals like copper, nickel and zinc. Some mines have already established systems to extract valuable minerals from tailings; these include DRDGold, Lonmin and Sibanye mines in South Africa. Dewatering systems are designed to be in close contact with tailings and if they can perform the dual function of recovering water while extracting metals, they would fully meet the demands of the mining industry. One of the most efficient techniques which can harness both dewatering and metal extraction is electrokinetics. Electrokinetics involves the application of an electrical current to induce the flow of water from the anode to the cathode in a process called electroosmosis. Electrokinetics also induces the migration of ions in a phenomenon termed electro migration. The metal cations precipitate at the cathode where they are collected and dried. This paper evaluates the viability of using an electrokinetic system to dewater and extract metals from tailings. Introducing a mineral extracting function could well be the key to increase the usage of tailings dewatering techniques by mines.

“…Metal extraction by electro migration is a two-stage process which begins with dissolution where the tailings are dissolved in a preheated acid or base solution (Jumari et al 2018). The solution is then agitated at a predetermined speed to ensure complete dissolution.…”

“…A escória de estanho está inserida na classe das escórias não ferrosas e é estudada como fonte para a recuperação de metais de interesse econômico, como nióbio e tântalo [45,46]. De acordo com a concentração de nióbio e tântalo, a escória pode ser classificada em distintos grupos: caso a soma das concentrações de nióbio e tântalo sejam superiores a 8%, considera-se alto teor; se estiver entre 8% e 5%, baixo teor; e se a soma das concentrações estiver abaixo de 5%, considera-se uma escória de muito baixo teor [47].…”

Ao bom Deus que é a base da minha vida. A São Bento, protetor dos estudantes, a quem recorro em orações para proteção e discernimento. Aos meus pais e minha irmã que são o meu alicerce e me dão suporte para que todos os meus sonhos se tornem realidade. Obrigado ao apoio e coragem para continuar. À família e amigos que deixei no interior do Rio de Janeiro com muita saudade, em especial ao meu avô, José Alves, que sempre enxergou o meu potencial e o quanto especial eu poderia ser. À Profa. Dra. Denise Espinosa pela orientação, palavras de motivação e confiança. Ao Prof. Dr. Jorge Tenório pela oportunidade de crescimento e confiar no meu trabalho. Agradeço também a Dra. Thamyres Cardoso pela contribuição no desenvolvimento do projeto e tempo de qualidade que construímos juntos. Ao grupo de projeto, Franco Garjulli, Vilson Conrado, Iara Anes e Giovanni Bonatti, que me acolheram e se tornaram família. Agradeço humildemente aos aprendizados e companheirismo que tivemos, e assim, fortalecemos e compartilhamos o ideal de que pesquisa não se constrói sozinho. Aos amigos que conquistei no LAREX, em especial, José Helber Vinco, Thamiris Auxiliadora e Jonathan Vinhal que, incansavelmente, me auxiliaram durante o mestrado. Agradeço pela amizade construída a Anastássia Mariah, Bárbara
