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 کاملBacterial populations within copper mine tailings: long-term effects of amendment with Class A biosolids.
AIM This study evaluates the effect of surface application of dried Class A biosolids on microbial populations within copper mine tailings. METHODS AND RESULTS Mine tailing sites were established at ASARCO Mission Mine close to Sahuarita Arizona. Site 1 (December 1998) was amended with 248 tons ha(-1) of Class A biosolids. Sites 2 (December 2000) and 3 (April 2006) were amended with 371 and 2...
متن کاملCase History of a Copper Mine Tailings Pond Reclamation in Ducktown, Tennessee
Cessation of mining operations in Ducktown, TN, left 800-900 acres of barren copper mine tailings. Revegetation activities had met with limited success. In 1998, efforts for revegetation of the tailings materials began anew. The objective of this case history is to provide insight into decision making processes which resulted in conversion of 800-900 acres of barren mine tailings into a vegetat...
متن کاملPrediction of Acid Mine Drainage Generation Potential of A Copper Mine Tailings Using Gene Expression Programming-A Case Study
This work presents a quantitative predicting likely acid mine drainage (AMD) generation process throughout tailing particles resulting from the Sarcheshmeh copper mine in the south of Iran. Indeed, four predictive relationships for the remaining pyrite fraction, remaining chalcopyrite fraction, sulfate concentration, and pH have been suggested by applying the gene expression programming (GEP) a...
متن کاملAccelerated weathering of biosolid-amended copper mine tailings.
Application of municipal biosolids to mine tailings can enhance revegetation success, but may cause adverse environmental impacts, such as increased leaching of NO3- and metals to ground water. Kinetic weathering cells were used to simulate geochemical weathering to determine the effects of biosolid amendment on (i) pH of leachate and tailings, (ii) leaching of NO3- and SO4(2-), (iii) leaching ...
