Inreverse flotation, columns have been used to remove fine gangue in a selective way, guaranteeing a high recovery of the main mineral in the underflow. Iniron oreprocessing, for instance, they are commonly used to remove silica.
Gold flotationis often overlooked as a processing option as the precious metal is viewed as being associated with the sulphide particles present in theore, even when a proportion of thegoldis free.Golddoesfloatreadily, however, and thefree goldcan be selectivelyfloatedaway from anore…

For extractinggoldfrom low-gradeores, heap leaching is practiced; huge heaps are sprayed with a dilute solution of sodium cyanide, and this percolates down through the piledore, dissolving thegold. There are very well defined rules for the safe and responsible use of cyanide – as laid out in the International Cyanide Code.Goldrefining

The melting point ofgoldis 1063 ˚C, which is a higher temperature than can be obtained by cheap torches and burners. By adding borax to the heavy mineral concentrate, the melting point temperature decreases, allowing people to meltgoldout of their concentrate and salvage. By using borax, no mercury flour is produced, andgold recovery...
If thecellair flowrates are not controlled individually, and air is fed to a group ofcells, butterfly valves are often operated manually to adjust the flow to eachcell. Lastly, Laurila et al. (2002) add that “flotation cellswith self-aspirating aeration mechanisms often do not have automatic airflow control.
