A flotation line for treating mineral ore particles suspended in slurry, including at least three flotation units arranged in fluid connection with each other for allowing gravity-driven slurry flow between flotation units, and a feed inlet for supplying slurry into a first flotation unit; wherein at least three flotation units are configured to be uniplanar, each flotation unit includes at least one flotation cell; and wherein the launder lip height of each uniplanar flotation unit is lower than the launder lip height of the preceding uniplanar flotation unit in the direction of the slurry flow, so that an angle of sloping between a first uniplanar flotation cell, equipped with a launder lip and being larger than 150 m3, and a last uniplanar flotation cell, equipped with a launder lip and being larger than 40 m3, is formed; and the angle is 1.5 to 10 degrees relative to horizontal.
