With rock gold, gravity separation teams up with other methods, such as flotation for the gold that's mixed with sulfide minerals, showing just how complex the ore can be. This mix-and-match strategy helps us get the most gold we can, showing just how flexible gravity separation is when we're dealing with different mining techniques.
