Dust Removal In Non-ferrous Smelting
Non-ferrous metal smelting — copper, aluminum, zinc, lead, nickel, tin, and rare earth catalytic materials — produces some of the most challenging flue gas streams in industrial air pollution control. The dust generated contains heavy metals (Pb, Cu, Zn, As, Cd, Cr, Se) with particle sizes ranging from submicron to several millimeters, often accompanied by acid gases (SO₂, NOₓ, HCl, HF) and high moisture content. Our comprehensive dust collection systems integrate baghouse filters, electrostatic precipitators, wet scrubbers, cyclones, and fume extraction hoods into a unified solution tailored to each smelting process — from concentrate drying and roasting to smelting, converting, and refining. Engineered with PTFE membrane filter bags, linear flow scrubbers, and advanced pulse-jet cleaning technology, these systems achieve particulate removal efficiencies exceeding 99.5% while recovering valuable metal dust for recycling. Fully compliant with EU BAT conclusions and EPA standards, our solutions protect worker health, ensure regulatory compliance, and enable clean production in the most chemically aggressive industrial environments.
