Exam 26: Counterfeit Cooling: in the Global Effort to Thwart Climate Change, Some Lessons Are

A mining operation extracts copper ore from the ground. Without access to modern smelters, they dig pits and use them as open-air smelters. They harvest nearby trees for fuel in order to produce the high temperatures required for separating the copper metal from other components of the ore, such as sulfur. Describe some environmental consequences of such an operation.

Question 1

Correct Answer:

Verified

The release of sulfur into the air leads to formation of sulfur dioxide, which forms sulfuric acid in the presence of water vapor. The resulting acid precipitation changes the pH (acidity) of the surrounding soil and water, negatively affecting the vegetation. In addition, deforestation further removes vegetation that serves to protect soil from erosion and to provide habitat for animal species in the area. As acidic soil and water run off into streams and creeks, the organisms in the water habitat are harmed as well.
