Process for treating Liquid effluents and Recovery of metals which comprises adding a solution of Amine in the ratio of 50 to 250 g / l in the liquid Phase with precipitation of MagnesWhat form of Magnesium Hydroxide and the Amine Recovery through depletion and rectification.

摘要

Process for treating liquid effluents and recovering metals, comprising the steps of a) equalizing the liquid effluent; b) ) adding sulfides and metal precipitation in the form of metal sulfides; c) separating solid/liquid from the metal sulfides obtained in step (b) and forming a liquid phase (10) free of metals; the process for treating liquid effluents and recovering metals further comprising the following steps: d) adding amine solution in a ratio of 50 to 250 g/L to the liquid phase (10) with magnesium precipitation in the form of magnesium hydroxide Mg(OH)2; and e) recovering the amine by depletion and rectification.
