Flotation Cells (Froth Flotation) were developed to separate and recover high-value Sulphide ores from low-grade ore bodies. The Flotation Cell is aerated to produce bubbles and agitated to keep the solids particles in suspension in the pulp. A flotation cell is an appliance in which froth flotation of ores is performed.

Gold can be enriched in sulfide minerals by flotation process to the maximum extent, tailings can be directly discarded, and the beneficiation cost is low. 80% of rock gold deposits in China are processed by this process. The flotation process mainly includes several stages, such as dosing, agitation, aeration and bubble scraping.

Gold cyanidation (also known as the cyanide process or the MacArthur-Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex.It is the most commonly used leaching process for gold extraction. Cyanidation is also widely used in the extraction of silver, usually after froth flotation.
