  • Froth Flotation of Iron Ores

    Froth flotation has been widely used in upgrading iron ores Iron ore flotation can be performed in two technical routes: direct flotation of iron oxides and reverse flotation of gangue mineralsCompared with the SLon magnetic separator, the operating cost of reverse flotation is much higher The flow sheet in Figure 916 provides an example of how to minimize the feed to flotation to reduce the total production cost The iron ore is composed dominantly of specularite with only about 05% magnetite, and the gangue mineral is mainly quartzReverse Flotation an overview | ScienceDirect TopicsA common process of removing silicates from iron ore is reversed froth flotation, where the silicates are enriched in the froth (tailings) and leave the system with the froth, and the iron ends up in the bottom fraction (concentrate) In practice reverse froth flotation usually encounters one of two drawbacks: either the iron ore bottom fraction contains a low level of SiO 2 — which in turn leads to a lowUse Of Polyols For Improving A Process For Reverse Froth
