Revegetation of a Mine Tailings Impoundment Using Municipal Biosolids in a Semi-arid Environment
Five separate test sites were established in 1994 to evaluate the use of municipal sewage sludge as a soil amendment and conditioner (hereafter referred to as biosolids) on the Kennecott Utah Copper Corporations tailings impoundment near Magna, Utah. Each site was divided into 16 test plots to evaluate four replications of the four rates of biosolids addition and incorporation into the taili...
متن کاملEvaluation of major constraints to revegetation of lead/zinc mine tailings using bioassay techniques.
The residues from the extraction of lead/zinc (Pb/Zn) ores of most Pb/Zn mines are permanently stored in tailings ponds, which require revegetation to reduce their environmental impact. This can only be done if the main constraints on plant establishment are evaluated. This can readily be done by field and greenhouse studies. To test this, the properties of different tailings from Lechang Pb/Zn...
متن کاملPlant-Mediated Changes in Soil N-Cycling Genes during Revegetation of Copper Mine Tailings
Nitrogen limitation represents a major bottleneck during the revegetation of mine tailings. However, controls over key nitrogen-cycling genes in rhizospheric soils under differential vegetation management remain poorly understood. The abundance and transcriptional activity of nitrogen-cycling genes and the enzymatic activity of nitrogen transformation are mediated differentially during revegeta...
متن کاملToxic metal(loid) speciation during weathering of iron sulfide mine tailings under semi-arid climate
Toxic metalliferous mine-tailings pose a significant health risk to ecosystems and neighboring communities from wind and water dispersion of particulates containing high concentrations of toxic metal(loid)s (e.g., Pb, As, Zn). Tailings are particularly vulnerable to erosion before vegetative cover can be reestablished, i.e., decades or longer in semi-arid environments without intervention. Meta...
متن کاملPreventing acid mine drainage from mine tailings
Mining activity always has high impact on its surroundings, being waste deposition the cause of multiple and complex problems to the environment. One of them is Acid Mine Drainage (AMD), causing acid water percolation through large areas in the mine site. Portugal was a prosper tungsten producer from the beginning of the XX century, having its apogee during World War II. Nowadays there are mill...
