why is froth flotation important dates

Some of the first laboratory studies reporting the application of froth flotation to clean coal date back to 1915 (Lynch et al., 2007). The first coal flotation circuit was developed and applied in the United Kingdom in 1920, while the first coal preparation plant utilizing flotation in the USA was established in 1930 (Aplan, 1999 Parekh, 2000).

Oct 01, 2012 The significance of froth properties in determining flotation performance is also well known. It is believed that rheology is an important froth property, because it can affect both froth mobility and froth stability. Mobility and stability are two important properties of froth in flotation.

Depressants prevent certain type of particles from forming froth during froth floatation process. A common depressant used in the froth floatation of lead sulphide is sodium cyanide. When the ore containing ZnS and PbS is subjected to froth floatation process in the presence of NaCN, then only PbS forms the froth.
