Mercury pollution due to gold mining in the Madeira River ...
Madeira River Basin is a gold-mining area, where in 1984 about 10 tons of gold were extracted from the river sediment. The gravimetrically separated heavy and fine particles are amalgamated with mercury and gold is recovered by heating the amalgam. Some 5-30% of the mercury is lost during amalgamation, mainly into the river, and 20% is released to the atmosphere by burning.

Pollution from Mining
Mining provides essential raw materials for an industrialized society. However, it causes serious pollution of surface and groundwater. Transferring minerals from deep below the surface to the surface promotes oxidation reactions. Oxidation of iron salts and of sulfur-containing materials in the presence of water leads to highly acidic solutions.
