The effect of regrinding on the design of flotation circuits
Although the design of flotation circuits has been studied since the mid-1970s, the possibility of including regrind circuits has been rarely addressed (Cisternas et al., 2018, Méndez et al., 2009a). Schena et al. (1997) proposed a methodology for determining the optimal network configuration of flotation plants, including regrinding …

A review of froth flotation control
Several authors, such as McKee, 1991, Laurila et al., 2002, agree that reasons for this include: a lack of appropriate instrumentation and technologies, and the old design of flotation plants; which consisted of numerous smaller cells making process control more complicated and cumbersome. As such, operator intervention was the only …
