Abstract
A flotation arrangement for treating mineral ore particles suspended in slurry includes a primary flotation line with a rougher part and a scavenger part. Overflow of at least one rougher primary flotation cell is arranged to flow directly into a rougher cleaner cell. Underflow from a first rougher cleaner flotation cell is combined into overflow from a rougher primary flotation cell downstream from the rougher primary flotation cell from which the first rougher cleaner flotation cell receives primary overflow; or into combined overflows from rougher primary flotation cells downstream from the rougher primary flotation cell from which the first rougher cleaner flotation cell receives primary overflow; or into overflow from an additional rougher cleaner cell which receives primary overflow from at least one rougher primary flotation cell downstream from the rougher primary flotation cell from which the first rougher cleaner flotation cell receives primary overflow.
