Air Emissions Management

Dust is the most common air emission at Barrick operations. We suppress dust emissions from roads, crushers and conveyor belt systems through the application of water to roads, the operation of mist sprays and dust collection systems at point sources, and the application of chemical surfactants at some locations.

The Company’s other significant air emissions occur at operations that process ore through mills, roasters, or autoclaves. These emissions include particulate matter, sulphur dioxide, carbon monoxide and mercury. Emissions from such facilities are controlled by the use of filters, scrubbers and other pollution control devices. Roaster operations at Kalgoorlie and Goldstrike are Barrick’s two largest air emission sources. Barrick is actively engaged in reducing mercury emissions.

We do not use materials that contain ozone depleting substances (ODS) except for fire extinguishers and some refrigerants and machine shop solvents, therefore emissions of these substances are minimal.
