flotation cells with, new 300m 3 flotation Outotec cells. The new rougher-scavenger circuit consisted of two rows (row 7 & row 8) with five Outotec TankCell300 each. The first two TC-300 work as roughers and the latter three as scavengers. Rougher concentrate feeds the cleaner

Supervisory control strategies evaluated on a pilot Jameson flotation cell

The Jameson cell was developed to be an alternative to other flotation devices, such as conventional mechanical cells and columns. Jameson cells produced small air bubbles without requiring spargers or external equipment. Intensive mixing, in the downcomer, with small bubbles favoured fast flotation without mechanical agitation.
