Depression of Arsenopyrite during Collectorless Flotation in Presence of Aqueous Metal Ions and Inorganic Compounds
Currently, the depression of arsenopyrite during the flotation of base metal mineral sulfides is being continuously studied to reduce its presence in sulfide concentrates of economic interest. In this work, the influence of aqueous metal ions (Fe<sup>2+</sup>, Cu<sup>2+</sup>...

| description | Currently, the depression of arsenopyrite during the flotation of base metal mineral sulfides is being continuously studied to reduce its presence in sulfide concentrates of economic interest. In this work, the influence of aqueous metal ions (Fe<sup>2+</sup>, Cu<sup>2+</sup>, and Zn<sup>2+</sup>) in concentrations of 5, 25, and 75 g∗ton<sup>−1</sup>; mixtures of aqueous chlorides (ammonium and magnesium) and aluminum sulfate (AS)–sodium silicate (SS); and the use of only ordinary Portland cement (OPC) in all concentrations of 0.05 to 0.6 g∗ton<sup>−1</sup> during the collectorless flotation and depression of a single-phase majority of arsenopyrite was analyzed. The results revealed a decrease in the hydrophobicity; its depression was greater with the use of OPC. At the concentration of 0.4 g∗ton<sup>−1</sup> at alkaline pH and a pulp potential of +0.067 V, in 0.5 min, its flotation was 15.4 % <i>w/w</i> and the cumulative recovery at 10 min was 46.4 % <i>w/w</i>. The arsenopyrite depression was as follows: OPC > mixed chlorides > ASSS. Fe<sup>2+</sup>, Zn<sup>2+</sup>, Cu<sup>2+</sup> ions activate flotation arsenopyrite. The solids obtained during the flotation were characterized using FTIR, and the functional groups responsible for the depression of arsenopyrite were identified. |
