Resumo: | Flotation is a mixture separation technique, characterized by the involvement of the liquid, solid and gaseous phases. This operation is used to separate hydrophobic particles from hydrophilic particles. It consists of adding air bubbles to the medium, which causes the hydrophobic particles suspended in the liquid to adhere to these bubbles, causing the formation of foam that can then be removed, dragging the particles of impurities with them. This work is of particular interest in the experimental study of the reverse flotation process in order to recover minerals of interest, such as iron minerals, present in tailings from the mining industry, aiming above all for reuse in future applications. |

Essa operação é utilizada para separar partículas hidrofóbicas de partículas hidrofílicas. Consiste em adicionar bolhas de ar ao meio, que faz com que as partículas hidrofóbicas em suspensão no líquido passem a aderir?se a essas bolhas, ocasionando a formação de espuma que podem ser então removidas, arrastando consigo as partículas de impurezas. Este trabalho apresenta particular interesse no estudo experimental acerca do processo de flotação reversa com o intuito de recuperar minerais de interesse, como por exemplo, minerais de ferro, presentes em rejeitos da indústria de mineração, visando sobretudo o reaproveitamento em aplicações futuras.
