concentrate the ore prior to this final stage of processing. With the advent of the flotation process and CIL/CIP in the early 20th century, there has been a push towards fine (<150 µm) processing for many gold and base metal ores. Reducing the whole of the ore to a fine size is energy intensive, so decreasing

The richest ore bodies (largely mined out) were only decimetre-thin sheet-like conglomerates that have been mined for >40 km along strike at grades of 20–40 g/t. Clearly, such a geometry of the ore bodies cannot be reconciled by post-depositional mineralisation through ascending fluids of whatever origin.
