Froth Flotation Column

The uncollected particles are removed through an underflow line As with a flotation column the froth may be water washed meaning the contact cell can also be used as a cleaner cell The contact cell is mainly used in rougher flotation circuits It is compact highly efficient simple to operate and has low energy and maintenance costs.
