Non-ferrous metals are those without iron. Common examples include aluminum, copper, zinc, lead, nickel, titanium, tin, and precious metals like gold and silver.

Key properties that make them valuable:

1. High resistance to corrosion and rust
2. Non-magnetic
3. Relatively low melting points
4. Good electrical and thermal conductivity
5. Ductile and malleable
6. Lightweight
7. Fully recyclable

Thanks to these traits, non-ferrous metals are widely used in automotive, aerospace, defense, electronics, power & energy, construction, medical devices, and mechanical engineering.

The production process is energy-intensive—smelting and refining require large amounts of fuel. Acids, alkalis, and other chemicals are also commonly used. As a result, manufacturing generates heavy dust and fume emissions. That's why non-ferrous metal plants depend on reliable, high-efficiency filtration systems.

Non-ferrous metal production (smelting, refining, recycling) generates high-temperature, corrosive, and fume-laden off-gases. Strict emission regulations (e.g., EU Industrial Emissions Directive, China GB 25467) mandate baghouse filtration as the final barrier before the stack.

Fugitive dust emissions occur at multiple points through the manufacturing processes in non-ferror metal plants. Main sources of emission include raw material storage and handling, roasting, smelting, refining, melting and casting. Main air pollutants emitted include CO2, CO, NOx, PM10, sulfur oxides (SOx), VOCs (volatile organic compounds), dioxins & furans, NH3, hydrochloric acid (HCl), fluorine & inorganic compounds, chlorine & inorganic compounds, PAHs and PFCs. The dust ladden gas flow generated during the manufacturing processes has the following characteristics:

1. High moisture level at high temperature
2. Acid corrosive
3. Fluctuated airflow velocity
4. High dust density

Thanks to these traits, non-ferrous metals are widely used in automotive, aerospace, defense, electronics, power & energy, construction, medical devices, and mechanical engineering.
