%X In this paper, waste rocks from the Yaoyuanshan ore deposit in Fenghuangshan copper ore field were taken as the main research object. Based on dynamical leaching experiments, the authors studied the factors affecting release and transfer of metals during the superficial geochemical procedure and the releasing and transferring characteristics of metals in waste rocks. Dynamic leaching experiments were made for detecting the heavy metal ion release law of waste rocks under different pH values and different lengths of leaching time. The results show that the leaching intensity increases with the decrease of pH, that the density of the metal does not necessarily decrease with lengthening of experimental time, and that the mine drainage is not exclusively acidic.
