The model for sulfide weathering in pyritic wastestone was studied based on the sulfide weathering rate in pyritic wastestone as well as relationship between the accumulating amount of sulfide weathered during pyritic wastestone weathering and some factors affecting weathering.The relationship is mainly based on the results of simulating experiment of pyritic wastestone weathering and analysis of field samples of the acid water. The model may be practical to predict the rate of sulfide weathering in pyritic wastestone of Dexing Copper M ine and the quality of the acid mine drainage generated by the wastestone weathering.
