Coarse and Fine Particle Flotation Recovery

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

Effects of coarse chalcopyrite on flotation behavior of

In flotation, fine particles do not collide with air bubbles hence the low recovery of fines to froth. Fig. 2 shows the experimental results of flotation vs model calculation results for fine chalcopyrite (D 50 = 2.3 µm) and coarse chalcopyrite (size: –106 + 75 µm). The results show that recovery of fine chalcopyrite was much lower than that of coarse chalcopyrite, i.e., around 27% for
