Preventing 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...
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 ...
متن کاملEnvironmental Compatibility of Lightweight Aggregates from Mine Tailings and Industrial Byproducts
A lightweight aggregate was produced by sintering the mixture of gold mine tailings, red mud, and limestone at 1150 ◦C. The physical (i.e., skid resistance, abrasion resistance, and bond strength) and environmental (i.e., leachability) feasibility of this aggregate was assessed to consider its potential use as a construction material for bicycle lanes. The skid resistance (British pendulum numb...
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 کاملPreliminary Investigation of Arsenic and Copper in Plants and Tailings at Telfer Gold Mine
The successful establishment of revegetation using native plants is crucial to help phytostabilization of mine tailings. To assess arsenic (As) and copper (Cu) pollution levels and the feasibility of using native plants in rehabilitation of mine areas, a preliminary investigation was conducted to measure As and Cu in mine wastes and native plants at Telfer Gold Mine. The top layer of soil/mine ...
