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. In oxidized ores, the surface of gold particles is often contaminated or covered by iron oxides.
Gold Flotation Production Line. Process Introduction. The flotation meth od is a widel y used technique for the recovery of gold from goldcontaining copper ores, base metal ores, coppernickel ores, platinum group ores and many other ores where other processes are not applicable. Flotation is also used for the removal of interfering impurities before hydrometallurgical treatment, for

flotation cell in copper gold ore processing plant. It is the first process that most ores undergo after mining in order to provide a more mineral processing plant, including sampling and analysis and dewatering. as in the case of gold and lead, the method has been generally suitable. . to adhere to air bubbles passing through a flotation cell or to remain in the to Mineral
Silver flotation process mainly applied for the recovery of silver and associated metallic minerals, silver including two categories: one is silver amp; gold, the other is copper, lead and zinc associated.
This paper presents the results of the effect of different collector combinations on gold and silver recoveries from lead and zinc ores by flotation. Best results were obtained on the use of Aero
Abstract. GENCOR Ltd. has pioneered the commercialization of biooxidation of refractory gold ores. Development of the BIOX #174; process started in the late 197os at GENCOR Process Research, in Johannesburg, South Africa. The early work was championed by Eric LiveseyGoldblatt, the manager of GENCOR Process Research who directed pioneering and innovative research into bacterial oxidation
Flotation is a method that is widely used in gold ore processing plant to process the rock gold,commonly used in dealing with highly floatable sulfide minerals containing gold ore flotation process can maximum enrich gold to the sulfide mineral, tailings can be abandoned directly, the cost of processing plant is low, 80 of chinas rock gold are used in this method.
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.
#0183;#32;Most of the reported fundamental work on the flotation of gold has been conducted using highpurity gold and goldsilver alloys with the purpose of determining collectorgold interactions and the nature of adsorption of collector ions or molecules onto the gold surface.
#0183;#32;A process routinely employed in the fire assaying of gold ores is the addition of silver prior to fusion of the ore in order to ensure that the silver content of the final bead is high enough to dissolve. This is called inquartation, and the separating of silver and gold by leaching with nitric acid is
Environmental Impact of Flotation Processing . Valuable minerals in an ore can be separated from each other, and from worthless minerals, by the froth flotation process. The need for a process to extract ore arose from major sulfide mineralization after the oxide ores had been depleted.
The ores from which silver and gold are recoverable by flotation divide themselves naturally into two general processing classes: ores in which the valuable minerals are those of the base metals, the precious metals being incidental constituents, and ores in which the gold and silver
#0183;#32;Flotation is usually used by large scale miners but can also be applied in small scale operations. It is a process that works best for processing complex ore types, especially ores that are difficult to process using gravity methods. In flotation, a mixture of slurry (crushed ore and water) and frothing agents are added into a flotation machine.
#0183;#32;The ground up ore is mixed with water to create a slurry, which is mixed with surfactants to increase the golds hydrophobicity. This mixture is placed into a tank or flotation cell filled with distilled water. Air bubbles are pumped into the flotation cell and the water is agitated.

Gold and silver are recovered by gravity concentration, cyanidation, or flotation from ores. The choice of those processes depends on the mineralogical characterization as well as gold and silver contents of the ore. Flotation has been applied on ores containing free gold and silver particles for many years.
