The disclosure further relates a use of a flotation arrangement, to a flotation plant and to a flotation method.
A flotation arrangement for treating mineral ore particles suspended in slurry is presented. The arrangement comprises a primary flotation line (10) with a rougher part (11) and a scavenger part (12). Overflow of at least one rougher primary flotation cell (111a) is arranged to flow directly into a rougher cleaner cell (210a). Underflow (42a) from a first cleaner flotation cell is arranged to be combined into overflow (51b) from a rougher primary flotation cell downstream (111b) from the rougher primary flotation cell from which the first rougher cleaner flotation cell (210a) is arranged to receive primary overflow (51a); or into combined overflows (51b, 51c, 51d, 51e) from rougher primary flotation cells (111c, 111d, 111e) downstream from the rougher primary flotation cell from which the first rougher cleaner flotation cell is arranged to receive primary overflow; or into overflow (42b) from an additional rougher cleaner cell (210b) arranged to receive 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 is arranged to receive primary overflow.
A flotation arrangement for treating mineral ore particles suspended in slurry is presented. The arrangement comprises a primary flotation line (10) with a rougher part (11) comprising at least two rougher primary flotation cells (111a, 111b) and a scavenger part (12) comprising at least two scavenger primary flotation cells (112a, 112b), and a secondary flotation line (20) comprising at least two secondary flotation cells (210a, 210b). A first secondary flotation cell (210a) is arranged to receive primary overflow (51 a) from at least one rougher primary flotation cell (111a), and a further secondary flotation cell (210b) to receive primary overflow (51 b) from at the least one further rougher primary flotation cell (111b). The further secondary flotation cell (210b) is arranged in fluid communication with a previous secondary flotation cell (210a), and underflow (42a) from a first secondary flotation cell (210a) is arranged to flow into the further secondary flotation cell (210b), or arranged to be combined with secondary underflow (42b) of the further secondary flotation cell.
This disclosure relates to an arrangement and a method for controlling a dewatering process comprising measuring values representing operating parameters of the gravitational sedimentation device and using the values as input values for a predictive multivariable model for predicting an operating state of the gravitational sedimentation device. The disclosure further relates to obtaining reference values for the operating parameters, determining at least one predicted output for an operating parameter of the gravitational sedimentation device, and comparing the predicted output to at the reference values to determine control values that will affect changes in operation of the gravitational sedimentation device.
