Flotation is then used for removing very fine particles <100µm in size, while the larger particles are typically removed from the process by screening. Air is then introduced to the slurry which creates a frothy mixture in which the movement of the slurry and the air bubbles force the ink to float to the top as a foamy substance.

Gold Mining Process Development Denver Mineral Engineers

The flotation process in general does not float free gold particles but is particularly effective when gold is associated with sulfide minerals such as pyrites. In a typical pyrytic gold ore, the gold is encapsulated within an iron sulfide crystal structure. Highly oxidized ores generally do not respond well to flotation.
