    This branch of chemicals will prepare the mineral surface so other reagents will be able to collect the metal For Conditioners and Modifiers, it may be simply cleaning the surface of the particles, as in the case of removing oxidization, or it may be a chemical that these are the chemicals that bind the mineral to the air bubble to be lifted away from the waste Activators will attach itselfFlotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate out This method of froth floatation is a method of mineral processing in which different minerals are separated selectively Such ores containing multiple metals such as lead, copper and zinc can be selectively extracted by using froth floatationWhat is Froth Flotation Process? byjusTypically three different types of chemicals are used in the froth flotation process: collector, frother, and modifier First, the collector is added to the iron ore slurry to selectively coat the iron oxide particles, making the surface hydrophobic The slurry then goes to a flotation cell, where air bubbles are generated using an impeller and aerator Figure 124) At this step, the frotherFlotation Process an overview | ScienceDirect Topics
