leaching is significant as it helps in removing the impurities like sio 2 fe 2 o 3 etc.it is the chemical method used for the concentration of ores. aluminium is generally extracted from bauxite ore this ore contains sio 2 iron oxides and titanium oxide as impurities. it is concentrated by digesting the powdered ore with a concentrated solution of naoh at 473-523 k and 35-36 bar pressure

in froth floatation processdepressants helps to separate two sulphide ores by selective prevention of froth formation by one ore and allowing the other to come into froth. for example in order to separate two sulphide ores (zns and pbs) nacn is used as a depressant. it selectively allows pbs form froth but prevents zns from coming to froth.

what is the role of depressant in froth floatation process

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.

the significance of froth stability in mineral flotation

aug 10 2011 0183; 32;froth stability has a significant role in determining the mineral grade and recovery achieved in a flotation operation. froth stability is depending not only on the type and concentration of the surfactant used but also on the nature and concentration of the particles present in the system.

explain the froth floatation process? - askiitians

froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. this is used in mineral processing paper recycling and waste-water treatment industries. historically this was first used in the mining industry where it was one of the great enabling technologies of the 20th century.
