The fabricated beneficiation system is based on the froth flotation principle whereby the mineral flotation is done by supply of air bubbles and rotating impeller in large mineral pulp bath. The mineral pulp to be separated is fed into the mixing chamber with the required flotation reagents, thoroughly mixed prior to its introduction into the flotation bath. The bath agitation is induced via the combination of installation of the electric motor powered impellers and the air from blower is introduced into the floatation bath. Mineral flotation process commences when the bubbles lift up the very light particles to the face of flotation bath after serious agitation and separated in form of froth. The machine design is centered on review works on the existing machines. The flotation cell was designed in simplicity based on scientific principles of froth flotation for efficient and economic minerals separation. On the laboratory scale, the cell is capable of separating about 15-25 kg mineral concentrates per day. The machine fabrication estimated cost is about N223,350:00.
