A review on the electrochemistry of galena flotation

Gu et al. (2002) studied the electrochemical oxidation of galena at pH above 12.5 and a potential smaller than 0.17 V and found that the oxidation products of galena were elemental sulfur and HPbO−. Moreover, elemental sulfur exceeded the oxidised lead species, which is beneficial to collectorless flotation of galena.

How to Make Lead from Galena Concentrates

The present method for smelting lead sulfide concentrates to produce lead is a pyrometallurgical smelting method that requires temperatures as high as 1,400 °C. Such smelting methods result in high lead and sulfur dioxide emissions. These high-temperature smelting operations will be unable to meet proposed emission standards.
