Abstract

One important critical value in mineral deposits is cutoff grade. The cutoff grade is defined as the value which discriminates between ore and waste with a given mineral deposit. In this study, the cutoff grade parameters such as SiO(2) and CaO% are examined by statistical distribution model. This paper shows a procedure for using the bivariate lognormal statistical distribution model with two uncorrelated samples to describe the SiO(2) and CaO% of Beylikova magnesite mineral deposit in Eskisehir, Turkey. After, it was determined that there are mean of SiO(2) and mean of CaO% involves the cutoff SiO(2) and cutoff CaO%, respectively. Finally, the bivariate lognormal distribution model with two uncorrelated samples is help to analysis in the cutoff grade parameters of mineral deposits.
