Flotation is a material separation method with air bubbles as the medium, also known as froth flotation.It is a beneficiation method with wide application and good effect in the separation of fine-grained materials. It is suitable for the separation of metal minerals and non-metal minerals, and can also be used for the recovery, separation and purification of many raw …

With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a century's practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities …

creating a flotation froth. However, most collectors used in iron ore processing produce adequate froths. The general types of these frothing collectors include long-chain carboxylates, sulfonates or sulfates, and amines as listed in Table 9.1. In practice the most widely used frothers in iron ore flotation are pine oil, aliphatic

the froth flotation process: collector, frother, and modifier. First, the "Collector" is added to the iron ore slurry for selectively coat the iron oxide particles, makes the surface hydrophobic. The slurry then goes to a flotation cell, where air bubbles is generated using an …
