Vertical Distribution of Cyanide and Heavy Metals in a Tailings Pond in Jilin, China

After long-term accumulation, weathering and rainfall of metals non-metals in tailings ponds, the chemical composition will change, surface heavy may gradually migrate to bottom layer, thus showing a cumulative effect. At present, distribution cyanide vertical space has not been reported. In this work, 12 sampling points were arranged for pond by grid method Jilin, China. The contents determined according standard method. results show that mainly Cu, Pb, Zn Mn (342.83 mg/kg, 571.09 610.15 mg/kg 796.63 respectively), concentration horizontal direction does change significantly. It should be noted concentrations zinc manganese did much direction. copper lead increased with increase depth. at site far away from human activities was higher 6.71 average is 2.5 mg/kg. addition, because unstable affected factors such as light rainfall, fluctuates.
