Emissions for manganese and mercury in method 3 are relatively close to the results in method 1, 1.96 and 3.34 times the values in method 1, respectively. Beryllium emissions in method 3 are only 4% of estimates in method 1 because a generic emission factor was used. For the four VOC compounds with source-specific emission factors, benzene ...
Lead in naturally found in many metallic ores and contribute to emissions during ore and metal processing (Table 4.20).The leading causes of lead emissions in mining and mineral processing in the United States are lead smelters, primary and secondary copper smelting, and iron and steel foundries.Lead can originate from nearly every smelting and refinery process including: milling, .
Some gold can be found by panning in rivers; heavy gold will remain in the pan, whereas lighter rocks and minerals float out. This small-scale form of gold mining has little effect on the body of water, but the large-scale practice of mining gold from ore can have tremendous negative effects on water quality.
