摘　　要：This paper deals with experiments of Cr(VI)reduction by natural pyrite from some metal mines.The experimental conditions are put forward in more details. Furthermore,the pyrite modified by heating from 400 to 500℃ is beneficial for the treatment of the waste water in pH value,sample quantity,sample grain size and the reduction time .The experiment results are helpful to purification of Cr(VI) bearing waste water in environmental engineering.This paper deals with experiments of Cr(VI)reduction by natural pyrite from some metal mines.The experimental conditions are put forward in more details.
