In The Days of gravity concentration, the art of ore dressing developed on the cardinal principle of saving the values at as coarse a size as possible. Flowsheets were designed which featured an alternation of crushing and concentrating operations. Thus an ore might be crushed to ½ inch, jigged to yield a finished concentrate and a middling; the latter being recrushed to ¼ inch, jigged a

Fine particle flotation (Book, 2007) [WorldCat.org]

To recover fine particles by flotation is very difficult due to their low flotation rate, which leads to poor recoveries and long residence times in flotation circuits. In this thesis, the reasons for the low flotation rate of fine particles are studied by focusing on the role of hydrodynamics and surface chemistry in bubble-particle collection. In this study, fine particle flotation was

Copper flotation is dependent on the mineral liberation grade, which is significantly related with the size distribution. It was shown that longer grinding time increased the Cu grade but decreased the copper recovery due to the presence of very fine particles. Lime and sodium metabisulphite, used as depressants, allowed to achieve a good flotation performance. It was
