Mining and Water Pollution — Safe Drinking Water

Heavy metal pollution is caused when such metals as arsenic, cobalt, copper, cadmium, lead, silver and zinc contained in excavated rock or exposed in an underground mine come in contact with water. Metals are leached out and carried downstream as water washes over the rock surface. Although metals can become mobile in neutral pH conditions, leaching is particularly accelerated in the low pH

Mining, contamination, and health in Ecuador IDRC

While small-scale mining is hazardous in and of itself, the processing of gold can be toxic. When miners hit a strike they can separate the gold from ore themselves or with the help of an intermediary. Alternatively, they can bring their find to one of the area's gold-processing plant. If the miners process gold themselves or through an intermediary, they invariably use an age-old process that

Heavy metals Wikipedia

Heavy metals are generally defined as metals with relatively high densities, atomic weights, or atomic numbers.The criteria used, and whether metalloids are included, vary depending on the author and context. In metallurgy, for example, a heavy metal may be defined on the basis of density, whereas in physics the distinguishing criterion might be atomic number, while a chemist would likely be
