Abstract
A flotation method for recovering valuable metal containing ore particles from ore particles suspended in slurry is disclosed. In the method, the slurry is treated in an at least one overflow flotation cell and the valuable metal containing ore particles are recovered by conducting the continuous upwards flow of slurry out of the at least one overflow flotation cell as slurry overflow. At least part of the slurry overflow is conducted to a further treatment step in a treatment system.
