Arsenic is currently removed from the solution by precipitation with ferric sulfate and lime. The first stage of the effluent treatment (pre-treatment) consists of adding ferric sulfate to the arsenic-rich solution, typically within 800–1500 mg.L −1 As (pH 4.5), to obtain a Fe/As ratio of 1.8 (by weight) and then raise the pH to 9.0 with lime. .

There were considerable quantities of copper and silver in the tested tailings that could form cyanide complexes during the cyanide leaching. The beneficiation plant at this particular mine in Mexico produces a copper concentrate, however their flotation circuit only recovers around 75% of the gold; the rest is lost in the tailings [14,15].
