Abstract
A flotation arrangement for treating mineral ore particles suspended in slurry includes a primary flotation line with a rougher part including at least two rougher primary flotation cells and a scavenger part including at least two scavenger primary flotation cells, and a secondary flotation line including at least two secondary flotation cells. A first secondary flotation cell is arranged to receive primary overflow from the at least one rougher primary flotation cell, and a further secondary flotation cell to receive primary overflow from the at least one further rougher primary flotation cell. The further secondary flotation cell is arranged in fluid communication with a previous secondary flotation cell, and underflow from the first secondary flotation cell is arranged to flow into the further secondary flotation cell, or arranged to be combined with secondary underflow of the further secondary flotation cell.
