Effects of coarse chalcopyrite on flotation behavior of ...
2021-3-15 · 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

2013-7-18 · Flotation works very well for particles that are typically in the range 20 to 150 μm in diameter, for base metal ores. In this range, it is possible to obtain quite high recoveries in conventional flotation machines. Outside this range, the recoveries decline progressively, whether it is with the very fine or thecoarse end of the size spectrum.
