EXPERT REPORT of DIMITRIOS VLASSOPOULOS

The Teck Cominco smelter located at Trail, British Columbia, has been in operation since 1896. Since at least 1930, water-granulated slag generated from the lead smelting operations was discharged to the Columbia River. This practice continued until 1995 when slag disposal to the river was eventually discontinued.

Zinc smelting - Wikipedia

Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point.At temperatures typically used for smelting metals, zinc is a gas that will escape from a furnace with the flue gas and be lost, unless …
