The flotation process is now used very extensively on gold ores, not only for concentrating the values without other processes, but also in conjunction with amalgamation, gravity concentration, or cyanidation leaching, to improve recoveries and to give lower treatment costs. In many instances, it is most profitable to recover the gold in the form of a concentrate, and either ship this product to a smelter, or amalgamate or cyanide
Flotation of gold and gold bearing ores ScienceDirect
A great deal of work has been reported on specific ores, but such studies rarely distinguish between the flotation of native gold and other gold minerals. Flotation of gold ores covers a broad field and it is a rather difficult subject to generalize on. Most problems in gold ore flotation are not connected with floating metallic gold.
However, due to the content of gold and other factors, the flotation of native gold has the following characteristics. Most of the native gold in the ore is in the form of fine disseminated,the gold particles must be finely ground in order to achieve the monomer dissociation.

Jul 23, 2014183; Since its discovery, froth flotation has been a major component for the processing of sulfide rich ores, including copper, coal, and refractory gold. In gold mining, froth flotation is used to separate gold from gangue by utilizing golds hydrophobicity.
Gold Ore Flotation Machine in Mineral Processing, Flotation cell, Flotation SF Gold Ore Flotation Machine can be used to separate non ferrous metal, ferrous metal, noble metal, non metallic mine, chemical material. It can be used in roughing, scavenging, selection or reverse flotation.
In the mining industry, the plants where flotation is undertaken to concentrate ore are generally known as concentrators or mills. For froth flotation, the ground ore is mixed with water to form a slurry and the desired mineral is rendered hydrophobic by the addition of a surfactant or collector chemical (although some mineral surfaces are naturally hydrophobic,  requiring little or no addition of collector).

The subject of extracting gold from flotation tailing arose a few years ago at the Cobar gold mines, as already mentioned, but in that case the difficulty was overcome by selling the mine, which contained highly silicious ore, to a company which owned a smelter, and had, or thought it had, plenty of basic ore
