| description | The Samarco Mineração, located between the cities of Mariana and Ouro Preto (MG), Brazil, 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: 2,52% of quartz in the concentrate and 12,67% of iron in the tailing. This indicates that, after
optimization, the desired especifications can be achieved. |
