Dispersion and Deposition of Particulate Matter from Stacks

Teck Cominco Ltd. is a diversified mining, smelting and refining group, a world leader in the production of metallurgical coal and zinc and a major producer of copper and gold. The company was interested in investigating the dispersion of particulate matter from its Trail facility into the surrounding area under the influence of diffusion, advection by the wind and settling effects. In particular, the company was interested in estimates of yearly release rates from particular release points which are very difficult and costly to measure directly.
