Geometallurgical Characterization and Automated

2016-1-1 · The concentration of gold in the Earth's crust and mantle is extremely low and highly variable, resulting in ore variability in many gold and copper–gold deposits. More importantly, gold in an ore may occur in two or three forms (i.e., microscopic gold, submicroscopic gold, and surface gold), making gold ore processing extremely challenging.
