Gold Ore Processing ScienceDirect

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. The objective of gold geometallurgy is to reduce and minimize the technical risk in project evaluation, plant design, mine planning, and production forecasting through geometallurgical modeling, representative sampling, and
