Secondary lead smelter feed materials usually require processing before being charged into a smelting furnace. Handling and transporting lead-bearing materials may expose workers to lead-bearing dust during:

• Raw Material Receiving and Storage
• Battery Breaking
• Charge Preparation (drying)
• Material Handling and Transport

Included in the National Institute for Occupational Safety and Health publication Mineral Processing Dust Control is the Dust Control Handbook for Mineral Processing, US Department of Interior, Bureau of Mines (1987).
