    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

    Froth Floatation Method Of Separation. In the froth floatation process, the role of the depressants is to separate two sulphide ores by selectively preventing one ore from forming froth.For example, to separate two sulphide ores zns and pbs, nacn is used as a depressant which selectively allows pbs to come with froth, but prevents zns from coming to froth.

  • FLOTATION Thermopedia

    "Flotation" is a generic term for a number of processes known as "adsorptive bubble techniques", Lemlich (1972); these are classified into foaming and nonfoaming separation methods. Foaming methods require the addition of surfactants to generate a relatively stable foam or froth which then acts as a carrier fluid during particle removal.
