Froth Flotation of Iron Ores

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 from iron ore

Flotation Collector

Flotation collector is a kind of organic substance that can selectively act on the surface of minerals to make the ore particles hydrophobic so that the ore can be catched by the foam and float to the surface of ore pulp thus being collected Flotation collectors have many kinds including xanthate dithiophosphate and so on

FLOTATION

Flotation is a process in Liquid-Solid Separation technology whereby solids in suspension are recovered by their attachment to gas (usually air) bubbles usually with objective of removing the solids from the liquid The particles most effectively removed are in the size range from 10 to 200 μm The particle-bubble aggregates that are formed have a density less than the suspension itself
