Falling prices for iron ore with lower quality than 60 % Fe have led increasingly to the design of iron ore beneficiation lines. General problems of water scarcity and risks with tailings dams have led to the focus shifting to dry beneficiation technologies. In the following article, current developments are examined and case studies referenced.
view moreOwing to the similarities in the physicochemical and surface chemistry of the constituent minerals, separation of zinc oxide minerals from their gangues by flotation is an extremely complex process. It appears that selective leaching is a promising method for the beneficiation of this type of ore. However, with the high consumption of leaching ...

It is worth mentioning that this separation method is used to separate minerals by exploiting the differences in their surface wettability [ 12, 24 ].

Beneficiation of low grade barite dumps interlocked with schist and slate gangue was studied using amine as collector (reverse flotation) to avoid the collector coating on barite. Instead of conventional flotation …

view more2014310 · The main routes of iron ore flotation were reviewed. Reverse cationic flotation is the most used flotation method of iron ore beneficiation. Ether amines and starches are usually used as collectors and depressant, respectively. Selective depressants for Fe-bearing silicates deserve further investigations.
