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,.
About 65 percent of such smelter capacity.copper smelting generates many types of materials flows.as copper concentrate flows through the smelting process, it leaves behind an altered mine deposit, sometimes mine waste, and mill tailings.fluxing materials, fuels, oxygen, recyclables, scrap, and water are input to the process.
