Abstract:
Nowadays, the mineral processing tailings disposal is a big problem due to the environmental degradation produced. The use of tailings dams is a globally used solution, but it generates very large impacted areas where soil, fauna and flora are equally suppressed. The present work proposes the mineral paste production with the tailings from phosphate rock in two stages. The first one was composed by the free settling of the material in presence of industrial flocculants. The second one was composed by the tailing filtration using a geotextile as filtration media. The used tailing samples were produced from Anglo American Fosfato Company, Ouvidor/GO unit. The results found were satisfactory for mineral paste production with solid grade around 35%.
