column flotation and its segregation was desirable. However, we were not able to isolate Krofta rejects from other reject streams. Thus, column flotation tests were performed with a blend of Krofta and Cleanpac heavy rejects. Rejects Column flotation at six-minute retention time removed 70–80% of macrostickies and wax from the process rejects.

Further, concentrate grades are higher in flotation columns compared to conventional cells, mainly because of the froth washing action which rejects many of the entrained particles (Yianatos et al., 1986, 1988; Falutsu and Dobby, 1989a,b; Finch and Dobby, 1990). A flotation column is a reactor composed mainly of a collection zone and a froth zone.
