Smelter Fugitive Emissions Reduction Study

Client: Lonmin
Location: Marikana, South Africa

Engineering study focused on reducing fugitive SO₂ emissions from converter and furnace operations at Lonmin’s platinum smelter. The study evaluated existing ventilation and capture systems, identified deficiencies, and developed conceptual designs for improved hoods, ductwork, and integration with the acid plant.

Key Objectives Included:

• Quantify fugitive SO₂ emissions byprocess area
• Assess performance of existing off-gascapture systems
• Develop options for improved furnaceand converter hooding
• Enhance integration with acid plant forbetter SO₂ utilization
• Provide CAPEX/OPEX estimates to guideimplementation
