Pre-Mine Prediction of Acid Mine Drainagetreams worldwide affected by acid mine drainage is not known, but over 7000 km of streams in the eastern United States are seriously affected by acid drainage from coal mines (Kim et al. 1982). In addition to low pH and high acidity, acid mine drainage from metal mines often contains dissolved heavy

Integrated Biological Systems for Effluent Treatment from Mine and Mill Tailingsedia on . and one of the interesting discoveries is that if treated municipal waste water is used for mineral processing, e.g., flotation, then the type of biological process applied in the municipal treatment plant is all important. Waste treated by conventional biofilters is more often than not un

Ecological Engineering: Biological and Geochemical Aspects Phase I Experimentsficult to overcome. The main goal of ecological engineering research is the development of methods which facilitate the establishment of vegetation cover types to serve as self-maintaining acid drainage treatment systems. Summarized below are the objectives and results of experiments on tailings and

Rehabilitation Measures at the Rum Jungle Mine Site season when much of the rain falls as localised thunderstorms. The average rainfall in the area is 1.5 m, most of which is confined to the period October to March. The mean temperature in the region is about 28° C with the mean monthly temperature varying between 29.6° and 25.1° C. The East Branch

Mine Tailings Reclamation. Inco Limited’s Experience with the Reclaiming of Sulphide Tailings in thewere assessed as to the area, type and vegetation cover associated with the waste material. It estimated that there were approximately 45,300 ha of land affected by waste rock, overburden or tailings (Murray, 1985). It is of interest to note that 7,300 ha or about 16% of this land had been revegetat

Environmental Management of New Mining Operations in Developed Countries: The Regional Copper-Nickels (US) to guide the development of major mineral resources of Cu, Ni, and Co in an orderly, comprehensive, and environmentally sound manner. In the early 1970s, the state recognized that exploration of the resource, which is located in northeastern Minnesota within the Superior National Forest (SNF)
