摘要

矿山酸性水是采矿活动造成环境威胁的主要原因之一，有效表征和预测废弃物的酸性水潜力对防治矿山酸性水具有重要作用。本研究对Görgü (Malatya)锌铅矿选矿厂废液池中新鲜废样的化学和矿物学性质进行了测定，并用结果来解释其AMD潜力。通过监测制备的悬浮液的某些性质随时间的变化，研究了废水在水中的变化特性。此外，在悬浮液中按一定比例加入黄铁矿精矿颗粒，评价其对AMD生成和蚀变的影响。分析和试验结果表明，该生废碳酸盐含量高，黄铁矿硫含量低，不具备AMD生成潜力。悬浮介质的pH值、电导率和金属离子浓度定期测定，所得数据非常有助于解释水中废物随时间变化的行为。将悬浮液中的液体耗尽后，对剩余的固体残渣进行化学和矿物学分析，并与原液进行比较。得出的结论是，充分的曝气和搅拌悬浮液是必要的，以显着改变废物。

Investigating acid mine drainage potential and alteration properties of Zn-Pb wastes from Görgü (Malatya, Türkiye) region

Acid mine drainage (AMD) is one of the main causes of environmental threats resulting from mining activities, yet efficient characterization and prediction of AMD potential of wastes play an important role in preventing AMD. In this study, the chemical and mineralogical properties of fresh waste samples, collected from waste ponds of the Görgü (Malatya) zinc-lead ore processing plant, were determined and the results were used to explain its AMD potential. Alteration properties of the wastes in water was investigated by monitoring certain properties of the prepared suspension with respect time. Additionally, pyrite concentrate particles were added into the suspensions at certain proportions to evaluate its effect on the AMD generation and alteration. Analysis and test results showed that the raw waste was rich in carbonate and poor in pyritic sulfur, and hence did not have the AMD generation potential. The pH, electrical conductivity, and metal ions concentrations of the suspension medium were determined at regular intervals, and obtained data were found very beneficial to explain the time-dependent behavior of waste in water. After the depletion of liquid in the suspension, the remained solid residuals were chemically and mineralogically analyzed to compare with raw waste. It was concluded that sufficient aeration and stirring of suspension is required for noticeable alteration of the waste.
