Abstract

A flotation arrangement for treating mineral ore particles suspended in slurry. The arrangement includes a primary line including at least two primary flotation cells, a first secondary line, and a second secondary line downstream of the first secondary line. In the arrangement, underflow from a secondary line is arranged to flow to the last of the at least one primary flotation cells from which the primary overflow was received, or to a primary flotation cell downstream of the last of the at least one primary flotation cells from which the primary overflow was received. The disclosure further relates a use of a flotation arrangement, to a flotation plant and to a flotation method.
