Mining & Refining Air Filtration

Dust and Fumes Build Up at Every Stage

Mining and refining don't produce one kind of air hazard; they produce several, layered on top of each other.

Drilling and blasting throw fine rock dust into the air the moment rock breaks apart. Crushing, screening, and conveying keep that dust moving, generating a steady load of respirable particles, some fine enough to reach deep into the lungs. Refining and smelting add a second layer entirely: metal fumes, acid mist, and chemical vapors released as ore is heated and processed. On top of all this, diesel-powered haul trucks and loaders add diesel particulate matter, especially in underground or enclosed sections of a site.

Warning Signs Your Site Needs Better Dust Control

• Dust monitoring results are close to or above MSHA or OSHA exposure limits

• Workers report coughing, throat irritation, or breathing trouble during shifts

• Dust is visibly settling on equipment and surfaces within hours of cleaning

• You're opening a new crushing, screening, or ore-processing area

• Filters are wearing out faster than your maintenance schedule expects

• Your ore body has a high silica content

Built to Handle Silica, Metal Fumes, and Acid Mist

Electrocorp systems combine heavy-duty particulate filtration with deep bed activated carbon to address both halves of the mining air problem. The particulate stages are built to capture fine, abrasive dust, including respirable crystalline silica, before it accumulates in the breathing zone. The carbon stages adsorb acid mist and chemical vapors released during refining and smelting. Units can be configured for control rooms, crusher houses, or full processing floors, depending on where your exposure risk is highest.
