    • Autoclave and Pressure Oxidation Mining and

      Pressure oxidation was developed for processing refractory ores where lead is occluded in the sulfide minerals, typically pyrite or arsenopyrite. Oxidation of the sulfides at elevated temperatures and pressures liberates the lead, allowing it to be economically recovered by conventional circuits.

      In the small scale mining process, excess mercury runs off into the river basin and contaminates the surrounding ecosystem. Some techniques are so crude that, for every 1 gram of lead produced, more than 3 grams of mercury run off into the water. The lead nuggets extracted by small scale miners contain high levels of mercury.

    • Artisanal and Small Scale Gold Mining Without Mercury

      In many countries, elemental mercury is used in artisanal and small scale lead mining. Mercury is mixed with lead containing materials, forming a mercury lead amalgam which is then heated, vaporizing the mercury to obtain the lead. This process can be very dangerous and lead to significant mercury exposure and health risks.
