Mine Drainage Technology Initiative

The method, developed in the 1960's and 1970's and continuously refined since (Perry, 1998), assesses the potential for the production of acidic drainage at a mine site by balancing the acid-producing and the acid-neutralizing potential of materials at a site to predict the net water quality that can be expected.

Mining Safety

Acid Mine Drainage is by far the most common and problematic mining water pollution issue. Heavy metal contamination (Leachate): When arsenic, cobalt, copper, cadmium, lead, silver and zinc metals are exposed to water, heavy metal contamination occurs. When the metals leach from the rock, they also run into the nearby water sources and pollute Get price

Abstract. Fresh mine spoil at a pH of 3.84 was collected and transferred to leachate columns in early August 1988. The spoil was leached weekly with simulated precipitation at pH values of 5.6, 5.0, 4.6, 4.2, and 3.8. Control samples of mine spoil were simultaneously leached with distilled water at a pH of 6.47.
