Videos of froth floatation process

Apr 28, 2021

May 22, 2021 What is froth flotation process Class 10? The Froth Floatation method is a method used for the concentration of metal ores. It is used for the concentration of sulphide ores. The ore particles become wet by oil while the gangue particles become wet by water. Air is blown in through a pipe and a rotating paddle agitates this mixture

    What is the role of depressant in froth floatation process?

    Depressants prevent certain types of particles from forming froth with bubbles. Due to this, we can separate two sulphide ores. For example, sodium cyanide is a depressant used for an ore containing ZnS and PbS. NaCN forms a layer of the complex Na 2. ] on the surface of ZnS and prevents it from forming a froth. Thus, it acts as a depressant

    Later ore particles are adsorbed by using potassium (as a collector) and ores come to the surface along with the froth. Note: Silver is a costly element and some of the ore settles in the bottom of the tub during the froth flotation process. Therefore, loss of valuable silver metal occurs through the froth floatation process

Other factor to consider is the presence of gangue minerals such talc or serpentine because they can create some problems during the rougher flotation

    The froth flotation process is more than a century old and was developed over a long period of time [8]. It takes advantage of the surface chemistry of fine particles—if one particle’s surface is hydrophobic and another is hydrophilic, upon generation of air bubbles, the hydrophobic particles tend to attach to the air bubbles and float

    Bubbles are formed due to this blown air. A rotating agitator at the centre of the floatation tank agitates the mixture and draws air into it to form bubbles. As a result, foam is formed which carries metal sulphide particles. The foam rises to the surface of water and floats. Therefore, this method is called froth floatation process
