Abstract:
In an example of a method for recovering lead from a lead material including lead sulfide, methane sulfonic acid is selected as a leaching acid for the lead material. The lead material is exposed to a solution including the methane sulfonic acid and i) ferric methane sulfonate or ii) oxygen, which leaches lead from the lead sulfide in the lead material, and generates a liquid leachate including a lead-methane sulfonate salt. The liquid leachate is purified, and lead is recovered from the purified liquid leachate using electrolysis.
