has been studying alternatives and/or more efficient equipments for their unit operations of Iron Ore Concentration Plants – such as the flotation pneumatic cells. With the following advantages: higher productivity
no moving parts
lower retention time and generating smaller bubbles. Pilot scale tests were performed at L.C.P (Laboratório de Controle de Processo) - Laboratory Process Control
a laboratory of Samarco. It was used the same samples that it is used in the mechanical flotation process – Wemco cells – in Concentrator I (CI) for these tests. The goals to be achieved with the essays were: quartz content in the concentrate below 4% in terms of iron content in the tailings below 10% - data normally obtained in industrial scale in the stages rougher
cleaner
recleaner and scavenger – CI. For the pilot-scale pneumatic cell
the best result achieved was: 2
after optimization
Flotation pneumatic cells.
