Abstract:
In this simulating eluviations experimentation of the waste gold mining ore,the analysis on component changes before and after the simulating eluviations experimentation of the waste ore is carried out.The results are as follows: the eluviations are in relation to the amount and intensity of rainfall.The more the rainfall has,the more eluviations are.But in the condition of equal amount of rainfall,the eluviations are more obvious with the rainfall amount smaller.The concentration of most components(or ions) exhibit increasing trend at different extents after the eluviations.In the eluviating liquid,the Pb、Mn
2+、NO
2-、F
-、Ca
2+、NO
3- oxygen uptake filter much more.Comprehensive analysis on the eluviating experimentation and local water environment show that rainfall eluviations causing the concentration of NO
2-、Pb hoist is one of the main factors that pollute the local water environment.Finally,on the basis of studying the waste gold mining ore in the Linglong goldfield;we propose a practical,scientific and rational method to prevent pollution and recycle the wastes.
