Base Metal Flotation. Dissolved Air Flotation
Nowadays most minerals are concentrated by froth flotation before its extractive process (pyrometallurgy, hydrometallurgy, electrometallurgy). Considering the importance of this process and the little information, this site has been prepared to give the basic ideas for a future investigation.
Froth Flotation has been used in mineral processing industry since the mid 1800's with
many of its broad-based applications to mineral recovery extensively developed between 1900 and 1925. Today more than 100
minerals, including almost all the world's copper, lead, zinc, nickel, silver, molybdenum, manganese, chromium, cobalt, tungsten, and titanium, are processed using froth flotation. Another major use of froth flotation is by the coal industry for desulphurization and the recovery of fine coal, once discarded as waste. Since 1950 flotation has been applied in many non-mineral industries including sewage treatment; water purification; paper de-inking; and chemical; plastic and food processing. The development of froth flotation continues with need to recover minerals from increasingly poorer grades of ore, as well as its non traditional application to other types of materials.
