Flotation is an economical and effective separation of refined gold technology, especially for these ores that are not suitable for other processes, such as ore, base metal ore, copper-nickel ore, platinum group ore, etc. Flotation is also used to remove impurities before hydrometallurgical treatment ie, carbon pre-flotation to purify low-sulfide and refractory ores for further processing.
At present, gravity , , heap leaching and cyanidation CIL,CIP are four commonly used recovery methods. Relatively speaking, the gravity method is the simplest process. According to the different mineral density and particle size, the ore can be achieved by the action of fluid dynamics ...
· Commonly Used Froth Flotation Reagents Collectors: Collectors commonly used in the flotation process of gold and silver ores include xanthate, black powder and butylammonium black powder. Kerosene and transformer oil can be used as auxiliary collectors. Oleic acid can also be used as a collector for gold-copper oxide ores.

Gravity separation is one of the oldest technique in mineral processing but has seen a decline in its use since the introduction of methods like flotation, classification, magnetic separation and leaching. Gravity separation dates back to at least 3000 BC when Egyptians used the technique for separation of gold.

· SF Flotation Plant is widely used for roughing, concentrating and counter-flotation of nonferrous metal that includes gold, copper, lead, zinc, nickel and molybdenum, ferrous metal and nonmetallic mineral. Working Principle of the flotation plant
can be used to separate nonferrous metal, ferrous metal, heavy metal, nonmetallic mine, chemical material such as , copper and recycling minerals. Each chute can inhale gas, sink magma, separate. No assiting equipments are required,and must be levelly installed. is easy to change the flow chart. The cycling way of magma is very reasonable.
· Flotation and Gold Extraction. Most methods of water-based gold extraction are dependent on gold’s lack of buoyancy to work. However, flotation uses a different property of gold to separate it from ore. flotation is a method for separating hydrophobic materials which will not mix with water from hydrophilic materials which readily mix with water.
Descriptions of the use of a flotation process have been found in ancient Greek and Persian literature suggesting its antiquity. During the late 19th century, the process basics were discovered through a slow evolutionary phase. During the first decade of the 20th century, a more rapid investigation of oils, froths, and agitation led to proven work-place applications, especially at Broken Hill, Australia, that brought the technological innovation known as “froth flotation.” During the early 20th century, it dramatically revoluti…
· The flotation method is a widely used technique for the recovery of gold from gold-containing and many other ores where other processes are not applicable.
The common gold extraction processes include gravity separation process, process, cyanidation, etc. process is the most widely used in gold extraction, but for different types of gold, we can choose flotation process combined processin order to improve the return on investment. The combined process between process and other processes can usually achieve …
