Recovery of Iron Ore Tailings byColumn Flotation

The exploration of iron ore in small mining companies results in a large amount of unrecovered fine material, representing 35% of the run of mine. Millions of tons of useful minerals are discarded every year into tailings, incurring operation costs, raising production losses and environmental impact. In addition to the disposal of 300 t/h of this material, millions of tons are already stored ...

The Influence of Froth Height in Column Flotation of

Jun 22, 2021 In froth flotation, the froth height, the entrainment and the drainage of particles affects recovery and grade. The aim of the froth phase is to transport all the hydrophobic particles that reach the pulp/froth interface into the floated and the drainage of the hydrophilic particles into the pulp. In this study, the influence of the froth height in the reverse flotation of kaolinitic ore was ...

Flotation columns getting the most from fine ores Metso

Oct 16, 2017 Flotation process within a column. Typically, columns are suitable for ores with a particle size bellow 150 m. Larger particles tend to be too heavy to be kept in suspension. This size limit may vary depending on the ore density. Lighter ores, such as phosphate, are amenable to column flotation at larger particle sizes.
