FLOWSHEET DEVELOPMENT FOR GOLD OREBODIES

GRAVITY SEPARATION This method of gold recovery has been practised for over 4,000 years, and was the only method of separating gold from its natural environment until the late 19th century. Many modern gold plants incorporate gravity circuits as part of their overall flowsheet, and it is estimated that about 10% of the new gold produced

In either case, the tail from the gravity circuit is usually returned to the mill-discharge hopper to conserve water and the concentrate is gravitated or pumped to the gold room. This desire to gravitate to the gold room influences the gold room location, as the concentrate is dense and requires a steep launder angle to prevent sanding.

Elemental gold has a specific gravity of 19.3, and typical ore has a specific gravity of about 2.6. All gravity concentration devices create movement between the gold and host rock particles in a manner to separate the heavy pieces from the lighter pieces of material. Panning is probably the oldest technique used for the recovery of gold.
