Flotation is the most effective solution, both technologically and economically, when
upgrading iron concentrates. Research regarding iron ore flotation began in 1931 …

ABSTRACT A tremendous amount of research has been done on refining the flotation
process for iron ore and designing the reagents which go into it. This paper reviews the …

Due to environmental issues and the restrictions imposed on mineral flotation separation,
the use of biodegradable and environmentally friendly reagents has gained widespread …

Various starches have been used as depressants in reverse flotation of iron ores. To date,
the effect of molecular structures of starches on the depressing behavior is still not clear …

Four different starches, namely soluble starch, corn starch, potato starch and rice starch with
different characteristics have been studied as depressants for hematite in cationic flotation …

Recently, beneficiation of iron from low-grade ores with high impurities has been a matter of
discussion. Flotation is one of the most effective technologies for the upgrading of low-grade …

Chlorite is one of the representative iron-bearing silicates gangue minerals existed in the
specularite ores which the traditional depressants are incapable of action in …

Reverse cationic flotation is the most known beneficiation method for the separation of fine
hematite particles from silicates. In this process, the depression of the hematite surface is an …

The interactions of polymers (corn starch, dextrin from maize starch, humic acid sodium salt
and sodium carboxymethyl cellulose) with iron oxides (hematite and magnetite) have been …

The reverse flotation of the iron ore with etheramine collector is significantly impacted when
the iron-bearing silicates and the kaolinite are present in the silicates gangue mineral …
