In the mid-1960s, flotation cells were commonly 5.7 m 3 (200 ft 3) in volume or less (Figure 12.65). In the 1970s and 1980s flotation machines grew in size and typically ranged from 8.5 to 28.3 m 3 with larger cells being increasingly adopted. Manufacturers in the forefront of the industry included Denver Equipment, Galigher, Wemco, Outokumpu ...
