Galena, or lead sulfide, the world's major source of lead ore, occurs worldwide; and, it is mined in many countries, including the United States, Australia and China. Lead ore comes from underground mining operations, where the lead ore seams are blasted out of the ground and transported to the
Not surprisingly, lead concentrations were also very high around artisanal lead mines where the ore had as much as 18% lead. We also found soil to be contaminated with mercury at gold processing sites where children were conducting amalgamation processes. In addition to the hazards of toxic metals in the ore, we noted very high silica dust exposures in ore processing.
Recommendation: There should be renewed support for advanced coal mining and processing research and development to optimize use of the nation's coal resources by increasing the amount of coal that is economically minable through technological advances that accommodate health, safety, and environmental requirements.
