Grade Control | SpringerLink

Abstract. In some mining operations one of the most important roles played by the geologist is the supervision of grade control. In an open-pit operation this involves the sampling of blast-hole cuttings produced by down-the-hole hammer drills and the classification of bench reserves into ore low grade or waste material or into various metallurgical types.
