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.

The main steps performed prior to the flotation process or froth flotation process is the crushing of rock minerals, grinding ore to a size change the amount of fine sand grains in order to liberate the metal to the separation process and to prepare the appropriate size to the next process.
the flotation process, ore is ground to a size sufficient to adequately liberate desired minerals from waste rock (gangue); it is conditioned as a slurry using specific chemicals, generically referred to as collectors, that adsorb to the surfaces of the desired minerals. This makes these mineral surfaces hydrophobic they tend to repel water and
