Predictive modelling of geometallurgical variables at Tarkwa mine, southwestern Ghana

Abstract This study applies a D-vine copula modeling approach to predict metallurgical recovery (Rec) from three key geometallurgical variables: semi-autogenous grinding (SAG) power index (SPI), resistance to abrasion and breakage index (A*b), and Bond work index (BWi). A dataset comprising 775 diam...
