Because of the weak metal bonding force, the native gold has the characteristics of small surface wettability and easy to float.

The production practice shows that the native gold and many heavy metal sulfide belong to the floating minerals,its easy to be collected by Xanthate Flotation Collectors.

However, due to the content of gold and other factors, the flotation of native gold has the following characteristics.
Get Quote
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.
Get Quote
Gold is often nbspdense associated with sulfide minerals, especially with pyrite,therefore, the sulfide minerals must be selected at the same time in the recovery of gold.
Get Quote
The relative density of gold is very large. In the process of flotation, the gold particles are easy to fall off from the bubble surface after contact with the bubbles.
Get Quote
In oxidized ores, the surface of gold particles is often contaminated or covered by iron oxides.
Get Quote
Gold has flexibility and ductility,in the grinding often showed flake and surface embedded a layer of mineral particles,to make the gold particle surface roughness.
Get Quote
In addition, due to the friction between the solid particlesnbspin the grinding process, especially between the steel balls and the strong grinding effect of gold particles, gold grain surface by iron and other metal contamination. All of these characteristics adversely affect the floatability of gold.

The flotation method is a widely used technique for the recovery of gold from gold-containing copper ores, base metal ores, copper-nickel ores, platinum group ores and many other ores where other processes are not applicable.

Flotation is the most widely used method in gold processing plant to deal with rock gold. It is mainly used to deal with gold ores with high floatability.
Get Quote
Flotation process maximizes the enrichment of gold into sulfide minerals. The tailing can be directly discharged. In China, 80 rock gold is processed by flotation for its low cost.
Get Quote
Whether the gold ore is applicable to the flotation method depends on whether it has better floatability.
Get Quote
For simple ore just containing gold, and the granularity of gold is uniform, and high floatability, simple grinding and flotation process is always the best solution.

If the ore contains some particle gold, gravity or amalgamation operation will be set in the grinding and classification circuit.
Get Quote
Gold is usually concentrated in mineral concentrate by flotation if the gold is contained in polymetallic ore.
