It is also a byproduct of many kinds of mining, mixing with water and heavy metals to form acid mine drainage. Sulfuric acid smells like rotten eggs. Contact with sulfuric acid can cause burns, blindness, and death. Treatment. Chemicals used at mine sites can spill on the skin and clothes, splash in the eyes, or be breathed in as fumes.

1. Distance from the exit of the plant and Water tracked from the wash can dry and leave fine silt behind that becomes airborne 2. Proximity to water and drainage Locating the wheel wash as far a possible from the plant exit will help tires to dry before trucks leave the plant. If possible, the wheel wash should be set back at least 1500 feet.
construct, operate, close and reclaim a gold mine in central Yukon. The Eagle Gold Project (Project) is located 85 km from Mayo, Yukon using existing highway and access roads.
