121· Froth flotation is the most important process to produce superconcentrates from low-grade oxidized iron ores. The efficiency of the process strongly depends on bubble size and froth stability, requiring the use of frothers. The flotation dynamics involves the collision and adhesion between bubbles and mineral particles in the pulp phase and the transportation of …

201511· Compared to base metal ores, iron ores are low-value products, and therefore, large tonnages have to be treated to make the upgrading process economically viable. This makes the flotation process, which is ideally suited for treating large tonnages of low-grade material, by far the best option for most of the ores currently being mined. However, as the …
