How can metal mining impact the environment? American

The impoundments associated with some of the largest mills, such as at open pit copper mines, can cover thousands of acres (tens of km2) and be several hundred feet (about 100 m) thick. Heap leach piles can cover tens to hundreds of acres (0.1 to 1 km2) and be a few hundred feet (about 100 m) high.

Discovering Metals A Historical Overview

of the discovery, these early extractive metal lurgists must be given credit for their powers of observation. Metal, specifically copper, could be won from ores by the application of heat, in this case the heat of a wood or charcoal fire. Extract ing copper from its ores is not an easy task. First the metallurgist must heat the ore
