BACKGROUND REPORT AP-42 SECTION 12.18 LEAD-BEARING ORE ...

Lead emissions from lead ore crushing and grinding processes are largely fugitive and are caused by drilling, loading, conveying, screening, unloading, crushing, and grinding. The primary means of control are good mining techniques and equipment maintenance. These practices include enclosing the truck loading operation, wetting or covering truck loads and stored concentrates, paving the road ...

Code of Practice to Reduce Emissions of Fine Particulate ...

Particulate matter is released from a number of operations, particularly during coke and bath crushing and grinding, which can generate significant emissions. These emissions are, however, strictly controlled through capture at the source and filtration systems. Anode baking is also a significant source of particulate matter, but the emission rate depends on the configuration of the furnace (e ...
