The estimation of important parameters at Choghart mine stockpile is accomplished by sampling specific parameters that allow detection of useful parts of the Low Grade stockpile. Huge amount of low grade broken rocks near the open pit can causes some environmental problem. Therefore, determination of dump parameters became important in this mine. In this research the estimation of Fe and P was fulfilled in low grade stockpile of Choghart. The Estimation of these two parameters (Fe \& P) can be used for mapping the...
