Development of a Sustainable Process for Complex Sulfide Ores Containing Anglesite: Effect of Anglesite on Sphalerite Floatability, Enhanced Depression of Sphalerite by Extracting Anglesite, and Recovery of Extracted Pb<sup>2+</sup> as Zero-Valent Pb by Cementation Using Zero-Valent Fe

Development of a Sustainable Process for Complex Sulfide Ores Containing Anglesite: Effect of Anglesite on Sphalerite Floatability, Enhanced Depression of Sphalerite by Extracting Anglesite, and Recovery of Extracted Pb<sup>2+</sup> as Zero-Valent Pb by Cementation Using Zero-Valent Fe

The presence of anglesite (PbSO<sub>4</sub>) in complex sulfide ores negatively affects the separation of Cu-Pb sulfides and sphalerite (ZnS) due to lead activation, and PbSO<sub>4</sub> rejected to tailings dams contaminates the surrounding environment with lead. To address...
