gravity separation placer fine gold concentrate plant

Basic Placer Mining for Gold, learn about the equipment

Gravity separation remains the most widely used recovery method to extract placer gold. Gravity recovery equipment, including gold pans, sluice boxes, long toms, shaking tables, jigs, and amalgamation devices, have been used since the time of the California gold rush, and many present day operations still employ the same types of equipment.

Extracting gold from gravity concentrates using grinding

This thesis presents a novel, chemical free method of extracting Yukon placer gold from various secondary and tertiary gravity middlings. This method exploits the differences in relative malleability rather than density. At a certain point in gravity gold processing, the middling material contains too many high density minerals to be amenable to further gold extraction through gravity
