Gold ores: Basically when a gravity process is able to recover more than 50% of gold, the potential presence of free or native gold is important. If the gold recovery is low, it is necessary to consider more alternatives such as flotation and cyanidation.

Gold extraction - Wikipedia

Gold extraction refers to the processes required to extract gold from its ores. This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore. Gold mining from alluvium ores was once achieved by techniques associated with placer mining.
