Mine Tailing
The sulfide mineral in tailing was oxidized during the dry season when rock was exposed to air. In the rainy season, arsenic was mobilized when the water table rose to the tailing waste (Rodríguez et al., 2004). The distribution of arsenic during mobilization exhibited spatial and temporal variability, depending on the regional geological feature.

At pH around 10.0, the adsorption amount of ATT on galena and sphalerite surfaces was ~1.2 × 10 −6 and 0.1 × 10 −6 mol·m −2, separately, which contributed to the enlarged difference of hydrophobicity and floatability between galena and sphalerite, resulting in a selective flotation separation of galena with ATT collector.

A review on the electrochemistry of galena flotation
Galena (PbS) is one of the most important base metal sulfide minerals and is a narrow band gap semiconductor. Galena often occurs with other sulfide minerals, such as chalcopyrite or pyrite (Zárate et al., 2012).Oxidation, reagent adsorption, and reactions between sulfide minerals and aqueous solution play a key role in mineral processing (Ralston, 1991).
