Briefly describe the structural characteristics of the mechanically stirred flotation machine

Floe foam flotation can therefore be used as a polishing treatment The flotation of mixtures of copperII leadII and zincII was carried out using FeOH3 and NLS The flotation of simple and complexed cyanides and mixtures of metal cyanide complexes was also carried out with FeOHz and NLS a pH of around 5 is optimum
